ok well before the rpm would hang when shifting before i changed my tps unless i moved my tps around and it would stop then it would just surge at idle so i replaced my tps yesterday and it dont have the surging anymore now it just has the hang no matter where i move it to any ideas?

 

What are you talking about? Your going to need to rephrase your question.

 

so your saying the rpm stays in place when u push the clutch in?

 

basically ya when im driving and shifting from gear to gear it just stays there and usually even goes higher in rpm when clutch is pushed in. it doesnt do it when cold only after it warmed up. i was thinking maybe idle control valve doing it but i dont want to go spend 150 on icv if its not the problem.

 

Have you tried pulling the ecu codes?

 

how would i pull the ecu codes? would i have to go to the dealer or could i just go to auto zone or oreilly.

 

Neither... go to Google, find steps, and then perform steps.
