Code p0303


P0303 is a misfire in cylider 3. This is almost always an ignition coil in this car. I would swap out all 8 with Motorcraft coils as well as spark plugs. If one is going, the others arent far behind and one bad one makes the others work harder.

p303 is a cylinder 3 missfire I woul first check the coil and then the ingnition module, Then if this dont work you could have a bad injector. If after testing and still no fix you should check the compression in that cyl.
