that make a whole lot of sense to me. however when i put a new idle air control valve on it, it acted the same. thanks for the tip though.
Yes but fitting a new idle air control valve does not reset the idle itself, you need to follow a set procedure to reset the idle, the throttle plate in a cetain position, the TPS sending the correct voltage for the idle position, it needs to know that the engine is warm from the temp sensor, if its in drive, if headlights or other current grabbing items might be switched on, that the mass air sensor is showing idle and so on, then the ecu will control the IACV, it needs to have the correct set of parameters to follow. ie: a set voltage from throttle position switch to tell it to idle.
Sorry I do go
