Ended up being a very well hidden crack in the wire way up the harness, aswell as a bad coil within the injector itself which got worse with heat soaking... after replacing both it seems to run without misfire. To anyone with this issue, be careful with removing the fuel rail, it can get seized...
tried plugging c2 in a few times and it seemed to not do much, couldnt find c104 at all but I will definitely be rechecking the cables this weekend and potentially be soldering new ones in, if all else fails i guess the mechanics the only way to go.. i very much appreciate the help, have a nice...
Just tested the injector wires and the fuse for dc voltage, for some reason they where all getting .17-.18 volts including cyl 5... shouldn't they be at 12ish ?
Defininitely will be replacing the wire soon, also the "bump in the road" gives me a few ideas... mainly because it acts alot worse if I dont let it cool down before starting it back up again from full heat. However it definitely isnt mechanical.
Thanks for the info, will definitely be using it tomorrow, however it would be easier if I could explain the issues properly, at this point it has to be the injector wire, pcm, or either the wiring going to the fuses/relay
2007 3.7L w/ around 190k
Cyl 5 misfire started a couple months ago, was intermittent and not as noticeable, popped random multi misfire code, along with cyl 5 misfire code.
(replaced coil and plug, problem nearly went away for a little bit and came back.)
started to pop the same codes again as...
07 Liberty - 3.7L - around 190k
Long story short check engine light popped up, ran codes and got cyl 5 misfire and random/multi misfire, I would get a rough idle and the exhaust would putter/backfire at idle however vehicle seems to run better when at medium to high rpm besides slight misfiring...
