Hi guys I need help I got a misfire on cylinder 3 and when I checked under the hood after the check engine light come on the nut that retain the coil on cylinder 3 unscrewed while I was driving. I put it back together with another nut that was at my mechanic school and the misfire was still there but I had to go home (~15km). When I got home I switched the coil 3 with the cylinder 2: still the misfire in 3 and same for the sparkplug. So I decided to take out the injector rail to see if an injector seal was broken and I saw that the rail close the cylinder 3 had some rust compared to the other but it didn’t look like it had a leak. I switched the injector 3 with the 2 and I putted back the injector rail and I have now a cylinder 2-3 misfire. After I took out the injector plug to see if I could hear something changing in the sound and there was no difference so I checked to see if the connector in the wiring harness was good and the ground didn’t worked on the one of cylinder 2-3. Anybody had this happened to them? I’m confuse because it all started with the coil detach from the engine so no spark but fuel in the combustion chamber so I tought maybe the cylinder outline was covered in gas so it didn’t had good compression but now the ground in the injector connector is broke at the same time the coil nut went off is kinda weird. And when I switched the 2-3 injector the two are now misfiring. Any help would be appreciated!!
