Im guessing it has to do with the IACV? I cleaned it awhile ago with carb/choke cleaner and maybe it fucked it up? I also heard that by unplugging the IACV will not throw a CEL on OBD1 cars? or maybe it was not having cooland lines will not throw a cel? *shrugs*

Anyway... why is it when i pull the FPR vac line off the IM the CEL goes away, it just idles fucked up? And also why is it that after driving for 1/2 hour or more after turning the car off and right back on the CEL is gone for like 20 mins? WTFFFF
