08 Aveo5 Shake or Miss
Hi,
Yesterday for the first time, I was driving down the road and I pressed on the gas, and the car for lack of a better description, jerked back and forth, not side to side. I thought, oh no, major problem. I know very little about the tech aspects of cars, so I need your help.
It seems to do it only when I start out from a stop. I was thinking either the transmission slips, or the engine missed, but I don't know what to do. I checked the tranny dipstick, and it had good level and was a reddish color.
What should I do? Also, yesterday was the hottest day ever that I have had the car on the road since I got it (86 deg) and I smelled a distinct smell of something burning or something like that.
I need to get to the bottom of this, as I don't want the car to be damaged beyond repair. It is very hot today, and I hesitate to even take the car out on the road due to fear of damage.
Please advise,
Viper

Re: 08 Aveo5 Shake or Miss
just from a stop? of with every shift?
i would check your engine/trans mounts, also control arms bushings.
did it seem like the power train jerked the car? as in the turning of the axles made the car move funny. or did it seem like a big thing shifted in the front of the car?
It could be engine related, but from your description i feel its the mounts..

Re: 08 Aveo5 Shake or Miss
Thank you soooo much for replying!
It seems to "jerk/sputter sensation" when starting from a dead stop or when it shifts big going up a hill.
How much would my dealer probably charge to look at it?
Please advise,

Re: 08 Aveo5 Shake or Miss
dealers charge like $100-120 an hour to "look" at it, unless your under warranty. and typically they don't know diagnostics unless they can read codes, but thats not all mechanics, some are very good.
you could pop you hood start the car and shift from drive to reverse, and watch to see if the engine rocks an excessive amount. also since you said it happens starting from a stop, listen for the "clunking" or motion noise while standing outside of the car, if the tranny is the issue you will see/hear the tires stutter in the case as extreme as your description. or if its the mounts you wont see it.
it could be a few things including your car not downshifting when you come to a stop. which could have multiple causes as well. before taking it to a dealer experiment how it happens, what you do that makes it happen, and practice making it happen on command (unless it all the time then they will be able to reenact it). so that you have more likelihood of them finding it faster to save you money.

Re: 08 Aveo5 Shake or Miss
Great advice.
Remember also the one symptom I mentioned that hasn't been addressed yet: the "burning" odor.
What do you think is causing this. That worries me pretty much the most.
Thanks
-
Re: 08 Aveo5 Shake or Miss
the burning odor, what did it smell like?
i can't say what is causing it definitively without actually having the car.
-
Re: 08 Aveo5 Shake or Miss
I have tested your theories and the following are my observations.
When looking at the engine while my son shifts from drive to reverse, the engine moves a little like a small rocking but I don't know what your definition of excessive is. I would say a half inch, maybe just a little more. I don't really hear any clicking but when I sit in the car and do the shifting, it to me seems like the car rocks forward a little too much, but again I am not sure.
Now, the road test. I hate to say this, but I was unable to reproduce the problem. But, I remembered another thing, that may or may not be related. When this happened yesterday, I was able to get it to pretty much stop misbehaving by turning the a/c off. This I just now remember. Also, the problem just "came on" suddenly yesterday for the first time ever. And, the car was really warmed up as well. Today I did not run it long enough to really warm up.
Your thoughts?

Re: 08 Aveo5 Shake or Miss
with that said, check you ac compressor clutch, turn it on and off a few times while watching the belt, if it is locking up, it would "halt" the small 1.6 engine when it can, cause a rough idle, put more strain on the engine causing a higher idle and rougher shifts and starting from a stop, etc, can also burn the serpentine belt for the smell issue.

Re: 08 Aveo5 Shake or Miss
Your 2008 Aveo should still be under factory warranty, why not just drive by the dealer and have them check it out.
-
Re: 08 Aveo5 Shake or Miss
not unless it has too many miles :(
i think rabbit is right on this one, its not overheating?
-
Re: 08 Aveo5 Shake or Miss
I drove the car today for about 12 miles round trip. Much to my dismay, the problem happened again with the a/c OFF. Here are my observations:
It seems to happen mostly when you start out going up hill. I am starting to think this is a shifting problem. There are only ~46000 miles on the car.
Also, it didn't start again until the engine was warmed up. The temp guage was a little bit below half way. (not very accurate)
What do you think now?
-
Re: 08 Aveo5 Shake or Miss
Now the symptoms have changed, i can say this though, if it was engine related i would hope you would have a cel by now. the transmission is 50/50 on a light sometimes.
what speed did you reach during the test run? do you know which gears you shifted into?
this is where i would need the car.
i think with your stated mileage and that its an 08, its under warranty.
-
Re: 08 Aveo5 Shake or Miss
mine would do this dealer made excuses
they said it was tps sensor and they replaced it but they didnt
(they cleaned it) i got use to jokeying the gas to keep it going once coasted almost a mile lol
finally i bought a used throttle body(caus u just cant get a tps for an aveo)
that fixed it ,,dealer did all kinds of stuff once they said valve cover leaked oil on plugs ,,so i paid them for a tune up for nothing
heres the long and short of it
alot of times if u drop hood hard the prop rod pops out gf holder hittn tps.
and it will crack it,,
causing u to have top replace throttle body
-
Re: 08 Aveo5 Shake or Miss
When car starts out, it is in lowest gear, and this is where the problem mostly happens. Once it shifts for the first time, it may or may not jerk.
Thanks
-
Re: 08 Aveo5 Shake or Miss
i had that happen to me several since i have a heavy foot and press on the gas al little to much and then let it go right away n the response of the car is like ok what the heck u wanna go fast or u wanna go speed limit so it jerks a bit. only time i smell burning is when im going up a steeeeeep hill on the highway and it drastically changes from 70 to 50 with the gas floored. other than that. do you have automatic or manual. if automatic make sure u check if u didnt put it into 2nd ive done that once and had the same reaction from the car plus the burning smoke.
-
Re: 08 Aveo5 Shake or Miss
Ok, today brings on another problem. Seems definitely major to me, and probably is related to the origional problem I posted about.
My gas tank was on empty, so I stopped to get gas. I always fill the tank up. Well, I pretty much just started fueling when the gas started coming out the fueling tube and spilling on the ground. I put exactly 2.0 gal of gas in and I could not put anymore in without it spilling over.
What gives? This acceleration problem has to be related to the fuel problem.
I eagerly await your response.
Thanks
-
Re: 08 Aveo5 Shake or Miss
fuel pump, that senser that floats around in there seems to be misreading the fuel levels, I dont know what else it could be
dlc, did you fix your problem?
-
Re: 08 Aveo5 Shake or Miss
i had exact same thing happen once i thought i was losing it ,,it freeaked me out but happened just once later on down highway i put 17 more in
..friend of mone says theres a chek ball that keeps peopl from siphioning gas
ands it can catch once n a great while
its a weird feeling though
-
Re: 08 Aveo5 Shake or Miss
its happened to me 3 times lol, i thought that could be that too, but the car has too many things going on with it lol, stealership time :(
-
Re: 08 Aveo5 Shake or Miss
considering i just bought this car a month ago, im unaware of what sensors it has. but clean the map sensor, check the transmission fluid (when running), do a compression test, check the spark plugs.
-
Re: 08 Aveo5 Shake or Miss
If the filler line or the gas cap has a leak this can affect the performance of the car and even give you a check engine light. This issue is caused by lose of pressure in the system, you will need to have this fixed. This will also throw you emissions off and cause you to fail if you require testing in you area.
-
Re: 08 Aveo5 Shake or Miss
I has still been "missing" or whatever it's doing. But yesterday, after doing it really bad for a little while off and on, the check engine light finally came on. I turned the car off and waited a half hour. When I restarted, the light was off and stayed off till I got home. This is the first time the light came on.
Also, the problem with filling it with feul it is gone. It was the problem with the pump, not my car.
Let me know what you think.
Thanks.

Re: 08 Aveo5 Shake or Miss
If the light comes back on again take it to your local autoparts store. I think they all do free code scanning these days.
-
Re: 08 Aveo5 Shake or Miss
Thanks for all of the replies. Here is what I found so far:
At first , the check engine never came on.
Then, a couple days later, it occasionally came on but was flashing
Then it became permanently on. Went to Advance Auto and tested the code.
P0001 or something like that. Description was cylinder one misfiring. That would make perfect sense.
I put a bottle of LUCAS fuel additive in to give it a liquid tuneup. I'll see if this helpa.
Please respond with you expertise.
Thanks,
Viper

Re: 08 Aveo5 Shake or Miss
How many miles on your spark plugs?
-
Re: 08 Aveo5 Shake or Miss
Don't really know if they have ever been changd since I got the car, so I would put ~48,000 miles on them.

Re: 08 Aveo5 Shake or Miss
Isn't suggested interval 30k? I changed mine at 30K to Iridium...

yup... i changed mine at 25k miles and the gap was pretty wide on them... i bwt you just need spark plugs... that's the first thing i'd do.

Re: 08 Aveo5 Shake or Miss
What are the best plugs for my car? Are there plugs that will increase performance and aid in feup economy?
-
Re: 08 Aveo5 Shake or Miss
Many plugs claim many things. I've never seen any make any noticeable difference. Copper plugs are standard, platinums last longer, iridiums last even longer. That is about the only difference.
-
Re: 08 Aveo5 Shake or Miss
The ones that were in my car originally were NGK copper made in korea, unlike the usual acdelco, so I just went from regular copper ngks to iridium ones. Supposed to burn hotter too, but like said above, nothing major you will notice.
-
Re: 08 Aveo5 Shake or Miss
2 things:
somebody said to clean the map sensor, but aveos are not map, they are maf.
and, sergea, how dare you tell these fine members that changing your spark plugs does not give extra hp. When I changed mine to iridium, I gained 10 million + horsepower. I was going thru tires like mad ;-)
is you out of warranty viper?

Re: 08 Aveo5 Shake or Miss
futz! I typed before I thought, we is map, not maf. Sorry :oops:

Re: 08 Aveo5 Shake or Miss
you fool :P
i wish i could get the readings though, i would want a maf #-o

Re: 08 Aveo5 Shake or Miss
Ok, this is the time to ask really stupid questions,
I popped the hood to look for the plugs. There are 4 wires coming out of the top of the engine. I figured, the thing where they hooked up to must be the plug assembly. I pulled one of the wires off, and it definitely is not the location of the plugs, from what I can see.
So, do I need to unscrew the top of the engine, take that black top off, and the plugs will be there?
Please, Please advise...
BTW: I got NDK Irridiums

Re: 08 Aveo5 Shake or Miss
"...I will spare you some of my keyboard warrior time..." -"8V 16V and all thing scene"
ok, the 4 wires that go acrossed the top of the motor (thicker, like 4guage amp wire) are what you want, but follow them to the valve cover (the big black square with the 4 wires coming out of it). Pull them out but only do 1 at at a time. After you pull the first wire ot you should be able to look down the hole and see a silver nub in the middle. Grab a 17 mm (?) deep socket and gently put It down over the plug and gently turn it until you feel it catch and fully resist you. Then carefully turn it to loosen it but be careful as you don't want the plug to break but know it will put up a good resistance. Turn it until the plug is free, gently put new plug into the well of the valve cover, then turn it to tighten it. Tighten it until it's nice and snug, take the long rubber grommet end of the plug and push it onto the plug until you feel it click and then repeat this 3 more times. The reason I want you to do one hole at a time is there is a specific order the wires go and I don't want you to mix them up, even tho they are all cut to length.

Or just go to your local store and ask them for a spark plug socket, and make sure you bring one of your new plugs to get the right size, there's two variations. They'll have rubber insert in them that will go right over that shiny piece that mike is talking about.

Just to clarify, he doesn't mean push it on to repeat the click three more times. One click per hole is enough. :lol:

I was trying to spare them the price of tickets, car crashes, and, of course, tires. ;)

Re: 08 Aveo5 Shake or Miss
Well, I replaced all 4 plugs with hdk iridiums.
I am happy to say the problem is fixed. No shaking, engine light off.
I got the code that told me the problem was cylinder 1 misfiring. So, changing the plugs fixed it.
Thanks for all your help given me to solve this for me, and all this whole situation cost me was $24.00.
Ciao,
Viper
