Gen IV Swap Stalling Witch AC On
Gen IV Swap Stalling Witch AC On I've done some searching but haven't found much on this issue for swaps that don't provide an "AC on" signal to the ECM. The engine in my Chevelle is stalling when the AC is on and I coast to a stop (clutch held down or in neutral). The RPM will drop to under 500 then overcompensate and spike back up to around 1500 before dropping again. Usually this cycle happens a few times until the engine stalls (all while I'm still coasting to a stop sign or red light). If the car is parked and the AC is on, the engine will return to idle after free-reving with no problem.
Some specs on the engine:
2010 L96 with stock heads and rotating assembly
Summit stage 2 turbo cam (running NA right now)
LS3 intake with the L96 flex fuel injectors and throttle body
E67 ecm running an 07 CTS-V operating system
T56
I can try to capture what's happening on a log if that will help.
