Why does my Toyota Celica have a high idle speed?
3 people found this helpful. Toyota’s also have a high idle (usually around 2K rpm) for a few moments after start up then it dies down to normal idle. Colder it is the longer the idle holds up. Now if it is super warm and it is idling high all the time then there is another issue most likely related to the above post.
Where is the idle air control valve on a Celica?
It’s a square hole on the front half in front of the throttle plate. It allows air past the throttle plate at idle, and the IAC (Idle Air Control valve) opens and closes depending on how the car needs to idle. The problem comes in when the PCV system is active.
What happens to the fumes in idle Celica?
These fumes have to go through the IAC at idle, and will condense into liquid form after a while. Unfortunately, it’s more of a sludge than a liquid, and this sludge gums up the IAC, limiting its ability to open and close (it’s only operated by a magnet), so your idle can become irratic after a while.

How can I tell if my Toyota Celica has a bad O2 sensor?
You probably have a vacuum leak or a bad O2 sensor. The simple way to figure out if you have a vacuum leak is to soak the vacuum hoses with soapy water. Start with one hose at a time. If none of these yield a leak check your EGR valve also. Unless your “Check Engine” light is on you may not have a bad O2 sensor.
How can I tell if my idle control valve is working?
To check if an idle control valve is working properly, start by turning on your engine and letting it run for a minute or 2. Then, when it’s at an idling speed, take note of the RPMs in your car. Next, turn the engine off and disconnect the idle control motor under your hood.
