Air Pump : PCM or Fuse??
My Z had the SES light going on and off so I replaced the AIR Pump but I still have the same problem.
My mechanic checked it via a Snap On Diagnostic Computer and it he said it's either the PCM or the relay.
I don't think it's the relay.
If it's the PCM, what do I need to do??
By the way, I have the HPP installed, do I have to reset to original settings??
Thanks~~

reset programmer
I would program back to stock and check it again. I had similiar problem where Mr. Goodwrench could not find problem either, he went from PCM, to MAF, and everywhere between. Anyway after he unhooked tuning he found it. I don't know but i would try it! Yah shoebox is right find out what code it is first. good luck1
