low idle speed causing shaking and CEL?
in park, my idle speed is low, car shakes and i can hear "puff puff puff" sound from the exhaust which usually result in an engine misfire CEL. (click on link for my idle speed)

when i turn the headlights and ac on, the idle speed increases and the shaking stops. Any idea whats happening? I've change spark plugs and wires but no improvement. How do i increase the idle speed to normal? I believe increasing the idle speed could help since i don't feel the shake when the headlight plus the ac is on(increases idle speed) See link for idle speed with ac and headlight on. I need help!!!

This thread will help with cleaning the throttle body, bore and plate.

I had the same issue with the low idle and I followed this thread and it went back to normal.

I bought a bottle of throttle body cleaner and removed the air intake hose. I then sprayed liberally on the plate as well as behind the plate. There wasn't much deposit on the plate. I also adjusted my fast idle which improved the shaking problem. Anyway what is the correct idle speed for the 2.5TL?

I thought it was 650. In any case, the JDM versions had much stricter tolerances for idle speed. The 3.2s without navi were to be set a 650 plus or minus 5, and the navi models were to be set at 620 plus or minus 5. USDM sticker says 650 plus or minus 50!
