Ok, my car is throwing codes p0300-p0304 and p1399, they are cylinder misfire 1-4 and random cylinder misfire. I've changed my distributor, spark plugs and wires, pcv valve, fuel filter, o2 sensor, ground wires, valves adjusted, valve cover gasket, compression test came out good, and injectors are firing. But I still keep getting these codes. The Car has no EGR because it's a SI model, and it's all the cylinders misfiring. Not sure where to go from here. Any ideas?
have the same problem?
