Engine Performance problem
2006 Ford Explorer 6 cyl Four Wheel Drive Automatic 46000 miles
Check engine light came on, and had the code read. It was a number 5 misfire. It runs bad a an idile and when I put a load on it, it runs wrose and has a surdge. When driving, it makes a back pressure sound. I have replaced the spark plugs, wire, coil, fuel filter, and fuel injector. When pulling the spark plug wires, when running, a change in engine on all wires except 5 & 6. I am now lost and don't know what to do next. Can you help?
