Spark plugs have been changed and fuel has also been changed. Code still coming up after reset. What else could be the problem?

Oh, let's see... :
Loose connection
Faulty injector
Faulty plug wire
Valve clearance, intake or exhaust

You will need to determine if you're losing spark or fuel when this misfire code is set.
