I have a 1998 Ford Expedition with a 4.6 liter V8 engine. The check engine light came on as the vehicle started to misfire or hesitate. I took it to a local mechanic to have the problem checked out. He told me I need new plugs and wires. I went and purchased those items and installed them. This did not solve my problem. So I took it to Autozone for the free check on it,and it came back cylinder three misfire. They told me to make sure the plug wire was connected good. I reset the check engine light and the light came on again. Autozone checked it again and told me cylinder five misfire. Again they told me to make sure the plug wire is connected good. Since then I have taken my vehicle to Autozone three more times with check engine light on. The machine has told them I needed a EGR Valve,Ignition Coil and EGR Sensor. I have replaced all the items I have listed and the problem has not been solved. Could someone shine some light on my issues. Thank You
