LOW IDLE RPM

2007 Toyota Corolla • 4 cylinder 2WD Manual • 68,000 miles

Hi, m having 1300cc corolla with twin cam EFI engine its RPM was 500 I went for tuning replaced plugs cleaned throttle RPM became 800 but after driving 100km it again came back to 500. Acceleration of car is good its not consuming engine oil.

It sounds like they did not get all the carbon out of the throttle body. Ask them to clean it again and see if it takes this time.

Any solution to this problem I have this same probleam after changing the battery, and changed maf sensor, throttle body cleaning everything and nothing like falling 500 rpm
