Too high and Too rich So I have this rebuilt Sr that Im trying to get track worthy. I can't pull codes from the ECu because the little srew just keeps turning. Symptoms: -I can't get the idle to come down much farther than 1500 (screwing the AICV all the way in). -It's running super rich -Rev limit at 4K with MAF plugged in -Unplugging MAF fixes ^that^ The main theory is a bad MAF. What do you think? Help is greatly appreciated, Jake
