What kind of mass air are you running? See how it runs with it disconnected. A friend of mine was having all kinds of idle problems, and drivability problems. Turns out his mass air was bad. It was a pro-m bullet set up for blow through. He returned it and got a univer. It has been running hard ever since. I know I am reaching here because his was a blow through mass air meter and yours is a draw through with the S-trim, but it's worth a shot. -Chris
