My jimmy has a very rough idle and is hard starting, rich exhaust and and after running for a while the catiltic converter runs very hot to the point where it turns orange. It stalls when driving. New plugs, fuel pressure regulater, cam and crank position sensors, and vaccum regulator. where do I go from here.

Did you use a fuel pressure gage? Any applicable codes? Do you have the spider fuel system?

Yes the fuel pressure checks out. The computer wouldnt pull any codes but for a time the check engine light blinked. I replaced the fuel pressure regulator in the spider last night and check out the rest.

What is the fuel pressure spec? With everything turned off, the pressure spec shouldn't bleed off with cpi. If it does bleed off, fund the bleed.
