OK, its only been happening for a while, but i have had all the mods eversince i put the engine in, and after about 10K on the engine, everything started, the only other thing i installed since then is my proflow maf and calibrator...however, stock maf acts same way.
the other thing that did happen is that my voltage was spiking one night, and my battery blew up, causing battery acid to get sucked into my intake, all the wya to the throttle body there was some corrosion...
and what is the imrc?!
