Just so you know your Celica is considered to be a fourth generation Celica. If you post there, it will be seen more, as there aren't enough visitors to the Classic section.


In regard to your problem. Look into a Throttle Position Sensor (commonly called a TPS). I had a similar issue on my old 1990 GT and this solved it.

When/if you buy the sensor, drive around for a half hour or so to calibrate the sensor. Your idle should then be normal.

If that doesn't solve it, it may need a tune up, mass airflow sensor, O2 sensor, etc.

I can't think of other stuff off of the top of my head and must leave for class.

Do a search for "Idle", which will yield many returns, but you may find something.
