Idle Surging not Hunting.
1988 911 3.2
I have had an intermittent issue with Idle Surging and then bouncing, once I give it a little gas 2K RPM's for 10 seconds or so the idle steadies.
No that the temps have dropped the surging is more common. When the car is cold in the morning no issues, if I drive the car and let it sit for a few hours
then I get the surging. I have adjust my idle and air mixture on the AFM. The ICV is new has a new HTC as well. Any other ideas? I have a cat bypass but still had the same issue with the cat on the car.
