I finally have an update. I got my pack of resistors in from Amazon and went to work. When I removed the green connector from the PCM, I quickly realized that pin 54 (primary fuel sender) was...

I'm not exactly sure why, but I have noticed every time I write to the PCM, the engine runs kind of like crap, rough idle, bank 2 tends to be lean (+5 or so long term fuel trim), but every time I do...

I ordered resistors, but will have to wait a few days for them to come in.
I picked up a purge solenoid from the junkyard and replaced it. Surprisingly, this made a huge different. When it was...

Just noticed you were in Bossier City. I was in Crowley running traps yesterday.

I agree on the injector expense. I run to a local LKQ yard around here, so if I did do injectors, I would grab 8...

I think my ECM fuel level at 0% is the driving problem. It's one of the enabling conditions for P0300 and I'm wondering if it's an enabling condition for a misfire counter.

I'm new to this, learning as I go. I'm a computer programmer by trade, so it's not that hard to pick up. I believe C5621 and C5622 allow you to set the # of milliseconds that the cylinder can be...

Thank you so much for the idea. I was running crawfish traps all morning and didn't have a chance to reply.

I ran an injector leak down test a few weeks ago and didn't notice much variation on...

I unplug the harness to the #2 or #4 fuel injector and I can feel the engine missing, but the tech2win misfire data and misfire chart never show a misfire.
I went to table C5622 in TunerPro and set...

I'm working on my 3rd CJ7 rebuild and this time I went with an LS swap. The build is mostly complete and I'm trying to learn how to tune the engine myself. It's a mostly stock LM7 out of 2004...
