ok so for the last few weeks i have noticed a slight hesitation problem when letting of the gas around 2k rpms as the rpms keep going down the car feels like its going to dye on me, giving me a slight jolt. now the only things i have done to her is air box mod and i run 89 in it all the time i only have 2,500 miles on the car so far, its a auto 2.2 2008. dose anyone have any ideas what the hell is going on. Or is it very common with all the 2.2's and nothing to worrie about.

 

hmmm not sure, hope its not a biggy tho!

 

me too

 

If its only got 2500 miles on it take it in for warranty and let them figure it out.

 

the people at my dealership dont like me cuz i bet the hell out of my old car so it was in the shop once a month and i was getting new front tires every other month lol

it was a 2004 chevy aveo i hated that car

 

it's actually a pretty common problem. I know they've got a tsb and a reflash up for it, but I don't think there's an actual fix for it.

 

what causes this to happen?

 

not positive. But personally I think it's a problem with the way the icm funtions. Our icms are more or less just dummies and the actual ignition settings are in the pcm. I think there's some idle control setting or something that conflicts with it.

 

well thanks for the info, i try and get up to the dealership in the morning to see if they will reflash it for me
