Hi.
I'm new to the forum but happy to be here and it looks like A LOT of great information is provided on the forums.
My quick question is:
What is the correct idle rpm's for a 1986 7.4 454 engine with A.C. suppose to be set at?
Thank you,
Rocco
650-750, There is usually a step up solenoid for when the AC comes on to raise the idle a bit.
