1999 Chevrolet Express 3500 5.7L Poor Idle Quality, Surge, hunts for idle
this van has a very severe hunt for idle in reverse. It acts up when backing up to hook on a trailer at idle in reverse. It hunts up & down 400 - 1200 rpm. The iac counts go up & down. I have a new maf on it, set the sync to 0 deg, trans line pressure is swing...
