2004 ecotec 2.2

Asked by Dec 18, 2012 at 09:47 PM

Question type: Maintenance & Repair

I have a ecotec 2.2 motor that runs pretty good, starts nicely, but after it warms up it seems to be slower to respond when hitting the throttle. When I hit the throttle when it is cold it responds very quickly. I adjusting the idol thinking that may be the problem, but it didn't help. Any suggestions?

I have a Ecotec motor and it responds the same, hot or cold. Perhaps the problem is in the transmission. Is it an automatic transmission? Have you checked the fluid level?
