doubtful… check the voltage on the tps if you have a multimeter… .its really easy, and its a 2 minute check as to if that’s the problem… ---

readings should be above .50 volts (key on, not running, throttle closed) i think u jump the top 2 wires. i know it’s the top 2 wires on a tpi motor. i never really messed with the newer tpi conecters. try driving with it unpluged. the pcm has a fail safe program that kicks on if there is no reading from it and see if it still has the same type of boog ---

kinda hard to test the tps without a scope. its nearly impossible to detect if it has a deadspot in it with just a voltmeter. just turn the key to the on position (engine off) put voltmeter at ground and signal wire. with your hand slowly open the throttle there should be a change in voltage. voltage should rise between .5 (closed) and 5v (wide open) when opening the throttle ---

i dont know off hand. easy way to find out is turn the car on and check with voltmeter. one wire should be ground, one signal and one constant 5v source. the signal wire should read .5 or around there with the throttle closed. the constant 5v will read 5v no matter wat position the throttle is in ---
