Post Plenum Pull Problem - ZR-1 Net Registry Forums

pantera1683 · 10-31-2010

I just finished with my plenum pull, changed alternator, wires, and coils. Now I have a misfire and backfire through the exhaust that is getting progressively better. My idle goes between 1300 and 750 and I do have a slight vacuum leak at the fuel pressure regulator that I will address this afternoon. I am just worried about damaging the car and want to make sure that the vacuum leak is my problem. Any ideas?
