Bucking / surge on Acceleration...
My Aveo has done this since new.
When I'm accelerating smoothly from a stop (5speed) in 1st and 2nd gear, you can feel the car pull / buck/ surge...not sure what to call it. Its noticeable, but not major.
I've switched brands of gas.
I was told that my ecm recieved an update when my car was new for driveability issues. Could this be related?
I'm past the warranty, so the dealer is going to try to charge me money, and will likely mess the car up further.
The one thing I have found about the problem, the more warmer and humid it is, the more the car will do this. The issue seemed to be gone all this past winter.
Anyone else have this? Found the cure?
Re: Bucking / surge on Acceleration...
change your spark plugs and wires
Re: Bucking / surge on Acceleration...
what mods have you done if any? last time you maintenanced the vehicle/what did you do? maybe bad batch of gas?
Re: Bucking / surge on Acceleration...
I think the only mod he's done is the OCC stickers...maybe it's that? :lol: j/k
You probably got water in your fuel, try HEET and see if theres a difference, it wont hurt anything if that's not it.

Obviously this probably isn't going to help this guy as it has been like 10 months since he's had his problem, but I had this same problem at about 40k and they had to replace the throttle body. I had a similar problem at 70k where it would happen, but only at about 3k+ rpms. ONCE AGAIN they had to replace the throttle body and also the o2 censor.
