SignUp Now!I'm assuming this is on the GNX you list in your sig.....you're a brave man modifying a GNX!
I'm up in Pryor....East of Tulsa. I have family in El Reno and make it to Thunder Valley every once and a while. Were you at the Shootout last fall?
I think OK hit it on the head. I bet your TPS is .46v or better. Get it under .46
The things to look at when you think your idle is funny are (obviously) idle RPM, which the chip controls...usually 750-775 RPM. The IAC #'s at idle should be 10-30 with the car in P/N and everything up to temp (160-170 degF). Your idle TPS voltage should be .40-.45 volts. Idle BLM should be close to 128...higher than 128 means that the computer is adding fuel therefore it's a bit lean (usually a vacuum leak somewhere)....lower than 128 means it taking fuel out and you're a bit rich. Also look at the MAF # at idle...should be between 4 and 6. Take a look at the O2 cross counts and make sure the O2 sensor is active....the O2 millivolt readings will be jumping all around and this is normal for a closed loop idle.
