Celica Forums General Discussion Exterior Low Idle? How can I fix it?

I have an 02 celi gt manual; when its in idle its real rough and low..it almost dies out sometimes. When I turn the a/c on it bumps it up a little...but isnt there a way to adjust this??? Thanks for you're help.

maybe disconnect the battery for a few min to reset the ECU... the ECU will relearn idle and that may fix your problem

New battery maybe...ive heard that a grounding kit will help w/ this. Also if your car is auto (maybe manual too im not sure) you could tighten the throttle cable.

Clean your MAF and then reset the battery, it fixed it on my car

ok well..there is a screw located under the hood (near the intake box) that you can turn up...but unless you installed an intake which sometimes messes with the idle..I would just get it checked...since you dont have a reasonable cause...

hmmm thats werd cause i put my a/c on it revs lower due to the pull it adds to the system


and yes you can up ur idle as explained by Sara but i'd have a garage look at it

Maybe you should check all your vacuum hoses? Sometimes they come loose (or you forgot to attatch one when putting in an intake?) That would be the first thing you should look at maybe. Also how many miles on the car? When was the last time you took it in?

If any of the above does not work, try tightening your throttle cable if you have an 00-02.
