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?
