I have been getting codes that say there is a problem with coil primary/secondary wiring on cylinders 1,2 and 4. I changed all spark plugs (6) and I also changed coil packs on 1 and 2. The code for 4 came after I changed 1 and 2 and now all three remain and there is definitely still an issue that i can feel and hear when running the engine. any suggestions?
did you set the plugs to the appropriate gap size?
plug gap,did you replace the plug wires.check fireing order make sure you did not cross a plug wire.
