yep idle surge

here's my thing... cold idles at 1000... warms up and surges in park at 1200-1500, place in drive back down to 1000 steady. i've done the vfaq and search. how do u test the tps. thx for replies guys.

Buy a repair manual, and get an ohm meter, the book is step by step.
Itll tell you to disconnect the wire and match the wires from the meter to the plug, measure the resistance.
