Hello, Well I have an 2003 Ford Expedition 5.4 with 142,00 miles. The issues I am having is about a week ago I recieved the check engine light code stating that I had a # 7 cylinder misfire. Well I changed that coil out with the accel brand and I also replaced the sparkplug. Everything has been fine until today when I recieved the same sputtering and hesitation with the # 7 cylinder misfiring code again. What could possibly be the problem ? Also I would like to put out there that for the last 4 years that I have owned the truck, I have had to replace the coils every year. The only brand I use is accel with motorcraft sparkplugs. I know this isn't normal. Can someone please help me or give me some insight of the possible problems? Thank you

Could be the injector on number 7 are you getting any other codes besides this one
check the wire to the connection on the coil... could be shorting out

Are there other brands besides ACCEL that are recommended? Thanks!
ok checked the codes and it's P308 which is cylinder 8. I pulled the cop and sparkplug and the sparkplug is wet. Tried to do the sniff test but couldn't really tell if it was gasoline or coolant. Here are some pics.

What are the gaps on the plugs?
Has your expy had its scheduled matinence? The Injectors are supposed to be cleaned/replaced at 90000. They may not be the problem but if they have not been cleaned yet they need it. I use the accel cops and have not had a problem, but I did have to fix one of the cops connectors. It broke right at the connector so it was hard to find.
