Can you post a log of the IAC counts and short and long term idle trims at idle? Is the set screw on the TB cracking the blade open too much?

I didnt log Iac but can say its adding fuel for the long term as its in the positive, which im assuming would suggest vacuum leak. Im gonna try a different approach to the pcv just to make sure 100% thats not an issue. tps shows its at .4% or .04% off top of my head. I will post the last log i took here shortly.

I was referring to the idle trims, not fuel, those PIDs are in the idle folder/sub-selection. The TPS sensor can be reset to read 0%, so it may be worth looking into. What are your desired air flow values at operating temp? If your IAC counts and/or idle trims are negative, I would back out the set screw on the throttle body. Ideal is 60-80 counts at hot idle.

I know that doesn't have probly any helpful info but thats what I was looking at. I'll see if I can get into the shop tomorrow and take a log of those pids.
Thank you for help.

You get a chance to log those PIDs?

Ok here is a log file with a bunch of IAC stuff. It looks like max was 140, 39...
I'll look at when I get home. Can you attach your current tune?
