Has anyone seen or experianced anything like this? On this 93 SC2 it runs like shit then dies when I hit the A/C button. Then after starting it with the A/C button pushed off it doesn't accelerate well at all, AFR reads lean, bogs clear down etc. Letting it sit for a while or disconnecting the battery for a sec then starting it makes it run normally again so long as I don't press the A/C again.n
The compressor isn't seized, I manual engauged the clutch and started it and it ran good until I hit the A/C again.
I'm leaning towards a short somewhere in the control circuit or possible ECM issue, but wanted to pick yalls brain before I tear into it a. ton more.
For kicks and giggles I did already put in a different IACV.
I switched PCMs with another one I had. It ran great until the A/C was turned on which instead of dying it just runs really bad even after turning the A/C off. Switched back to the factory PCM and it does the same things as in the original message.
