I have, but like I said, when I spray it with starting fluid, it clears it up for a couple days. Doesn't add up

 

No it doesn't. O2... Iat and coolant temp sensor as stated earlier. Have you tried unplugfing the tps and starting it? Though I doubt tps its worth a try. With it unplugged it should start and idle fine. Just won't rev right.

 

O2 and coolant are new. I've unplugged the sensor but didn't try to start it.

 

like Catty said if you haven't pulled the IAT and checked/cleaned it, I would give that a try. It's part of the fuel/air mixture equation. Mine ran a lot smoother when I pulled mine and hosed it down with TB cleaner. It had a orangeish film on it and cleaned up nice and white/blue. It does stick down in the intake manifold, so that may be getting a light misting from the starting fluid?

 

After reading all this, its the tps! The tps gets a signal from the ecm/tcm to bump the idle when in gear? Makes since why it doesn't act up in neutral? Yes?

 

Maybe, lol. Thanks for all the input guys! I am gonna mess with the ecm codes and the iat and tps sensors on tuesday. I'll post what I figure out, or dont figure out. Thanks again.
