    Default 20v Idle problems when engine temp is warm.

    hey everyone the 20 valve idles fine until the engine temp gets to just under half way on the engine temp guage. it then idles at 500rpm and then stalls. it will start back up no problems but will struggle to ilde for about 15 secs and then stall again.

    would the problem be the AFM?? or something else.

    most probably its the idle air control valve.
    while the engine is warming up it would probably hold the RPM higher. most cars do, once the ECU detects that the engine temp is at oprating temp, it would stop the cold start cycle and default back to idle RPM.
    if the idle control motor is faulty or dirty it may not work correctly and hense the stalling.

    I would remove the idle control and clean it. Refit it and see how that goes for you.
    (this will help also)
