hey guys. my 2.2 ecotec had a weird problem starting on saturday.
while driving the car will all of a sudden start stuttering and lose power while under load and driving. but it only does it once and a while and for short times.
there doesn't seem to be a pattern. for example. went to a friends house a town over, and had the cruise set. every couple minutes it would bog down and slow down. hit the clutch, give it some gas and away it went.
it's kinda like when your traction control kicks in. sounds exactly like that.
on the way back. worked fine the whole time.
not sure if it does it under load or not. i think it might of a couple times at a stop light.
so i've narrowed it down to a couple things.
1. fuel pump starting to go bad?
2. plugged injector?
3. my negative post on the battery might not be making a proper connection. i recently took off the post and things were slightly corroded, but i reinstalled anyways.
4. bad 02 sensor
things that have changed recently. on wednesday i installed a new front 02 sensor, and disconnected the negative post on the battery to clear the computer, and attempt to get rid of the cel.
filled car up saturday afternoon. it was right empty (been this way for about 2 weeks now)
i dont think it's bad gas since it had trouble starting saturday morning. fired up and died right away.
i'm going to take battery posts off and clean them up first, see if that fixes it.
any other ideas?
sorry for the long post. trying to give alot of information
