Is there an idle button on a Celica?
It’s just there to reduce low RPM engine noise. It opens between 3000-4000 RPM to let more air into the engine, and there is no adjustment for it (it’s controlled by the engine’s vacuum). The only way you can adjust the idle on the Celica is to get the Apexi PowerFC.

Why does IAC idle become irratic 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. The vapors also condense on the throttle plate and inside the intake manifold, so spraying them clean will improve airflow and performance a bit.
What happens when you raise the idle on a car?
No, if you up the idle manually, the ECU will eventually reset itself and bring your idle back down to being too low. The ECU has set parameters for idle and open throttle percentages, which is how it knows if you messed with the idle (same reason it idles high when the engine is cold, or when idle rises when you turn on the AC).
Why is my Toyota Celica engine running rough?
Hook them into the plug connectors and crank the engine. All 4 plugs should give sparks. If there are glitches in the electrical system,then engine would run rough but would not die totally. Could be any of the smaller vacuum hoses not plugged in or leaking. Check all those quarter-inch vacuum hoses.
What should I do if my Toyota Celica engine dies?
Anyone trying to troubleshoot or fix cars should buy an engine scanner cheap like $20 in eBay. Then at least you have some ideas what failures are and possible root cause. If the engine just die instantly and totally, fuel starving is very likely. Check and make sure the fuel pump is working and the wiring has signals to the pump.
