Misfire in cylinder 4 2.2 ecotec
I have got the engine in this car after rebuilding it due to bad piston rings. Before I rebuilt the engine the car fired on all four cylinders and was somewhat smooth running other than bad compression. Now that I have the engine in the car I have it started and running But with a misfire in cylinder 4.I replace the four coil packs and had the same issue. This morning I went out to the junkyard and I got four different Ignition control modules. I brought them home and changed all four of them out and had the same problem through all four of them so I doubt buying a new engine control module will fix my problem. I swapped out all the spark plugs try different spark plugs and all of them come out covered in gas in only cylinder 4. I don’t have the help I need right now to confirm that I have spark or not in cylinder 4. In the meantime I am asking for help and ways of helping me troubleshoot this misfire beyond my own knowledge.
