I have an 02 saturn vue 3.0L that has a constant cylinder 1 and 3 misfire. It was brought to me by another mechanic because he has replaced the following, spark plugs, coil packs, intake and gaskets, injectors, computer, o2 sensors, fuel filter, crank sensor, and the misfire still presists in the same 2 cylinders. The compression in those cyliders are good I checked that out but im lacking conclusions on what the problem may be. It runs fine until the engine light starts flashing then it misfires. Any suggestions?
