350 tpi iroc randomly running rich?
Hey everyone, I'm helping my dad work on him iroc he traded for a few years ago. The car runs great, but it idles at 2k rpm. There are fuel psi and an air fuel gauge. At random the car starts idling lower, and running really rich. I have to pump the accelerator to get it to slug down the road. I hear misfires some but not all the time(only while running rich). The car is perfect on the timing though. Any suggestions? I was told something about the cold start coming on, or the iac, any suggestions? Thanks in advance.
