ok when i try to lower my idle to check timing , i unplug the IAC but my idle remains high above 1k rpm im not sure if i need to do anything before that or after that , to my knowledge i need to have to unplug the IAC and turn the car on and it should ethier die or struggle but my car turns on as if IAC is still plugged in lol , ill shoot a video if needed ?? i have set tps at 0.94v tested it by opening the throttle plate and the voltage raises and lowers steady no jumping around or anything , and the screw behind the throttle plate is not even pushing the blade open its all out , im lost to what i need to do next ?
