I'm chasing a surging idle so decided to check the tps so i took two screws out and took the top off and it appears to be a thumb screw there. What do i do with that? Do i turn it to set idle or what. Sry for the noob question.
You don't remove the TPS to adjust it. All you need to do is losen the 2 screws so the sensor can move back and forth. Probe the green wire with a DVOM and move the sensor around until you get close to a volt. I did mine yesterday and got it at exactly, .099.darthcual said:I'm chasing a surging idle so decided to check the tps so i took two screws out and took the top off and it appears to be a thumb screw there.

You may also want to clean the IAC valve with some carb cleaner.

That doesn't mean it is good. Take it off, clean the inside really well.darthcual said:IAC is brand new. It cracked in half about two months ago so i had to replace it.
