Okay - so I picked up a 4.6L 94 LX so that I can put my SC in the garage for the winter. It had a CEL when I bought it. Probed it for codes and came up with misfire #2 cylinder. So far I've replaced the coil pack with a spare, flipped #2 and #8 cylinder plug wires, replaced all spark plugs and even replaced the #2 plug wire. Reset the PCM after each item and the CEL came back.
Today I decided to flip the #2 fuel injector with an injector from #4 cylinder. Reset PCM and the same P0302 code came back. There's fuel getting to #2 cylinder since #4 didn't misfire AND the #2 plug is wetter than the rest of the plugs. Is it possible that the #2 cylinder injector stays open more often than it should? The reason I ask that is that the car idles a little choppy but the car runs REALLY well at high speed/high RPM.
Next thoughts/steps for me include testing the wiring to #2 injector along with checking the recommended items in the OBD2 diagnostic routines in my Ford factory manuals. Anyone have any deeper experience with this along with some possible suggestions?
