About a year ago my 08 focus started misfiring. I took the spark plugs out and there was oil in the wells, so I replaced the gaskets around it as well as the spark plugs. When I took the valve cover off I cracked it (missed a bolt and tried to pry like a damn fool) and I’ve seen oil building up around that crack. I put some jb weld over it and it’s still leaking, so I think part of the issue could be air getting in. When I replaced everything and connected the ground wire, the car wouldn’t start. It’d crank but not run. When I disconnected the ground wire it started. I had everything diagnosed by ford and they said there was a short in the wire and it was only used for sound muffling or something like that. They also told me I had oil in my spark plug wells (I didn’t) and that I had a crack in my valve cover which I already knew about, so I only learned about the wire issue. I replaced the valve gaskets again and I’ve still had the misfiring problem. It got to the point my car would stall at low speeds (like parking lot stop and go) and the check engine light and battery light would come on. I had the codes read at autozone but nothing came up. The stalling hasn’t happened for a while and I didn’t change anything when it did so I’m not sure what caused that. I swapped the coils from my girlfriends focus and the misfiring stayed the same. The clips that connect the coil to the plug wires (I hope that makes sense I’m not sure what it’s called) wouldn’t clip right away on 3/4 coils, but when I pushed them together harder they would stay. I’m not sure if the clips are bouncing around and that’s the problem or if it’s more the air getting in. Any advice would be appreciated, thank you!
