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 well as an open injector/ injector circuit code, and it would go from not misfiring very badly from work and back to misfiring badly and shaking past 1500 rpm in 3rd or 4th later on when i go elsewhere from home, and this would be the same case every day for the last 2 weeks. (changed injector fuse, asd fuse, and switched asd relay with rad fan relay which seemed to fix the bad misfiring and bring it back down to the slight misfiring.) besides this i tested the old injector fuse with a test light and would not get any power, although all other fuses did, and i also tested the plug/wire going to injector 5 and got no light, however that seemed to be the case for the properly working injector wires as well. This makes me think that it is something to do with the wiring, relay, fuses, or pcm resulting in poor fuel mixture and some sort of electrical problem causing everything to happen. i have plenty of freeze frame data stored but i am not a mechanic so i cant read it lol. Long story short, f Chrysler and their electrical issues. Anybody have the same issue and have any knowledge to share?
