Po302, po507: Replaced all of the following: fuel pump, cat. Conv, fuel injectors (no.2, no.6, no.5), fuel pressure regulator, pcv valve, IAC sensor, HEI coil, plugs, wires, cap, rotor, fuel filter, all three O2 sensors, VSS, Ignition control module check was good, EGR valve stem clean, new vacuum lines, no.2 spark plug replaced again just to rule out a factory defect, TPS check good, CPS check good. I've given her lots of love. All work has been completed within the last 8mo. I should have a lean machine at this point. Exhaust doesn't really seam to have any tell-tale signs of water (white smoke) Hope to avoid replacement of head gaskets. Could the intake manifold gasket be a cause of the misfire, and not the head gasket? Since there is a PO507 with a PO302 wouldn't this be more likely?
have the same problem?
