Reply to "Idle adjustment DRLA 40s"

I ran 8-9 degrees at idle with the Megajolt. No trouble with idle speed at all. If the distributor advance plate is hanging up, yeah that would do it.

I did have my cable set with ZERO play cold when I first built the car, and when the engine warmed up, so did the throttle housing. All the sudden it was idling at 1500-1800. I loosened the cable and it permanently fixed it.

Disconnect the cable and see what happens when it's hot, if the idle goes down. If you can't get it to idle low close the darn idle air bypasses. Either that or you have a vacuum leak. I'd rock the intake manifolds and see if they've worked loose.
