Drummer Posted April 10, 2008 Report Share Posted April 10, 2008 Something is making my GP have throttle surge at random times and I'm not quite sure what is causing the problem. Sometimes it will pick up to 3000 rpms and slowly go to 1000, and other times it revs to 2500 and goes back to 1000. Would the ECM be a possible culprit?

Crazy K Posted April 11, 2008 Report Share Posted April 11, 2008 this happened in the 94 3100 sedan. the Q2 was the culprit. Have you got a check engine light? Quote Link to comment Share on other sites More sharing options...

Addicted to eaton Posted April 11, 2008 Report Share Posted April 11, 2008 Correct me if i am wrong But can't they get ploged?. That sounds like the map sincer too. Does the car ever idle like a old cammed up musle car? Does it have any cracks in the vacume lines under the hood. It could be alot of things.

Drummer Posted April 11, 2008 Author Report Share Posted April 11, 2008 the car idles smooth until it warms up then it idles rough. I always thought that was weird cause every 3.4 i've owned never idled like that, but then none of them were manuals. Quote Link to comment Share on other sites More sharing options...
