Good Evening/Morning 6GCelicas members. I just bought my 1994 Celica GT-s I think its an S don't know for sure. Anyways when I start the car up for the first time in the morning when I go to work it starts up no problem. But when when it first idles it steams like it might shut down it runs a litttle rough. But when I put press down on the pedal to get the rpm up it goes away. Now if I run it for like 20 minutes st8 on the road and park it and go back it won't do the rough idle. But when I leave the car for more than 12 hours of the engine shut off it does the rough idle on first start. The reason I'm asking for help here is I truthy love this car of mine. I use to have all my life cavalier Gm's cars and my friend sold me on this car. I would like to post you some pictures of my car and show you why I love it. I'm in love with my celica and hope this isn't an engine problem here. I would like to thank 6gCelica for the great forums and would like to buy some stuff for my car which I've been asking on the forums. Any help here would be great.
Thanks for your time. |

could be a faulty cold start injector, i had it happen to a friend of mine with a celica.. kind of the same problems you discribed.

94-99 Celicas don't have cold start injectors its normal for our celicas (or most toyotas) to idle high on cold start up the ecu was programmed to do that to help warm up the engine faster once its warmed up the idle should go down if yours is running rough and sounds like its gonna stall on cold start up you might want to test and clean your IACV=Idle Air Control Valve located under the throttle body thats what controls the high idle on cold start up they get dirty over time and most likely just needs to be cleaned.

it almost sounds like an intake problem.. my dad has an old prelude that idles rough, but its carbed instead of fuel injected.. but the main problem is that the engine isnt gettin enough air, hence why it idles rough... im not an expert, im just sayin the intake may be some worth looking into.. try holding oxyegn right by the intake and see if it changes.. if it revs higher then u dont have an intake problem
