Good Morning Gentlemen and Ladies if there are any,

2007 Ram 1500 5.7 Hemi check engine light on with a misfire on cylinder #7 P2320 Ignition Coil 7 Secondary Circuit-Insufficient Ionization code. Found a rodent had chewed through #7 coil wiring and #7 fuel injecter wiring. Repair the wiring to both and I still have a misfire on #7 with the P2320 code. Checked to make sure I have 14v. Checked the wiring between the PCM C1 pin 5 and fuel injector pin 1 on #7 the PCM C1 pin 3 and pin one of the #7 coil the wires checked good. Pin 2 on both the coil and the injector have 14v. Used a O-Scope and I have the firing pulses on cyc #1,#3,#5 for both the injector and the coil. Nothing on #7 coil or injector. At this point I'm leaning toward the PCM channel #7 is bad. I suspect the wires shorted together and took out channel 7 on the PCM. My question is where can I send the PCM for repair. I've read horrible reviews on Flagship One. I was hoping someone has a company they trust.

Thank you in advance.

I have used "Go ECM" in Grand Prairie, TX a few times to repair the NGC PCM's that are used in the 2006-2008 DR trucks with good results.
