Rough idle Options

[Unholy]

Recently I have been having a ton of problems with my celica shaking only when in drive when stopped. If I put it in neutral it mostly goes away.


I haven't really started looking at much to fix the problem because I just didn't know where to start.


If you need more info just ask.

It's possible you're tranny isn't disengaging the way it should when you press on the brake. Maybe a faulty switch. I assume this is an automatic by the way you're talking?

When is the last time you cleaned out the throttle body and linkage? Maybe there is some dirt preventing the IAC valve from opening the butterfly enough.

But you said it runs fine in neutral, so that leads me to believe it's transmission related. Check your fluids, a possible tranny oil change is in order, and have a shop check your shift solenoid, (if they exist on these cars, never dealt with an AT Celica directly before) or any other sensors that may be in line to brake to tranny relation.
