AC Clutch Engaugement

Howdy all. It's been a while since I've posted. The truck is still running great. I've got an issue with my AC clutch engaugement. When I turn on the AC the clutch doesn't engauge like it should. It'll hit and kick out immediately. If I rev it just a few RPMs it stays engauged. My freon pressures are correct and it cools nicely. It just won't stay engauged at idle. My idle speeds in B4603 are higher than stock. The only AC related differences I could find over stock where in G0108 and G0109, which I don't think would affect it. I don't see anything that says "don't enable AC clutch belowe xxx RPM". Any ideas?

Hi blsnelling,

Log the pid STATE00 to see if it offers any clues.

Sometimes if timing is to low at idle it will cycle the clutch when engaging , pulls to much timing and causes the PCM to cycle clutch , something to look at .
