Hi this is my mothers car, since she bought it she has a problem with the idle speed. I have changed the clutch, air flow sensor, throttle body, idle control valve, air recirculation valve, the only thing I haven't changed is the ecu! Is there anything else I could be missing?

Hi, I got 2002 galant LS 2.4L!

I also changed the air flow sensor and air control valve. Doesnt seem to idle to car. RPM is @1400 while parked. And during drive its @700 and when I start A/C RPM drops as well. Service engine light is also on. Dont know what to replace!

I was wondering if you got it fixed.

It sounds like the throttle cable needs to be adjusted, here is a guide to help and instructions below for the adjustment.
