2003 SPI Misfire
My daughter's Focus has been having intermittent misfiring at around 45mph when accelerating. Then a couple days ago the MIL started flashing and registered a 0302 and 0316 code. It seems to get worse when accelerating.
I replaced the crankshaft position sensor but the miss is still there. I am going to replace the plugs and wires, but I'm not sure where to go from there if that doesn't fix the problem.
Any thoughts, hints, suggestions would be greatly appreciated!!
