    Need help! My old 93 Corolla Gli has problems with its RPM. Minsan it goes 1500 rpm on Normal Operating Temp then goes back to 1000. Then minsan bumababa ng 800 rpm at may "palag". Panu ko susulusyunan ito? Anu papa-ayos ko?

    sir, if your engine is EFI, theres a chance that your IACV "Idle Air Control Valve" or the TPS "Throttle Position Sensor" is worn out or clogged (the IACV) or needs to be adjusted (the TPS). also check for Vacuum leaks as well.


    aite, peace.
