I checked the obd codes and ifound in the unit marked A in socket one a 2-2-3 code a missing signal to\from Idle control vlave. I pulled it off and pulled it apart and cleaned it out. It drove a lot smoother w/o the hesitation liek before when the engine was cold. The idle still faulters a little bit when started up and the check engine light is on. So do i still need to replace the idlecontrol valve to remedy the small faulter? I also got a code form the diagnostic unit marked B in socket two, 1-2-2. what does this code indicate something abotu a temperature sensor?? any help always appreciated thanks
