thanks for the tech info, i made a harness to allow trouble shooting of the signal values of idle control system.
today i will record values from cold to hot and see if i can identify the fault.
do have one question that i cant read and find, on the idle control valve,does the air flow indicator point toward the engine or throttle base? i have 2 89300t3 and found the idle control valve installed in oposite directions.
thanks again
