How do you know its time to either clean it or replace it...I have this weird idle after the car is warmed up and I do a re-start it will sometimes not idle or it will surge up and down...Also I want to check my TPS voltage too...any help would be great!

Run the engine codes first.


There is nothing to adjust on the TPS sensor. If there's no code...there's usually no problem
