So I have had the car for about a year now and at first the idle was fine but after a few months it started to jump from 1000-1500. I then did the basic tune up (oil change, spark plugs, wires, distributor cap/rotor, flushed the radiator) after doing so it ran fine for about 2 weeks. Ever since then the car idles for 1250 -2800 when stopped. I have tried to clean the FITV, IACV, and the throttle body. The car is still idling the same way. What else is there to try to resolve this issue?

 

Same thing was happening with my 93 accord and IT TURNED OUT TO BE MY pcv was clogged, simple fix
