Found the FPCM, connector looked good and clean, reseated it, still have same issue. I've got an FPCM, an LPFP, injector, and fuel rail o-ring set on the way. All together the parts cost less than a trip to the dealer, even after I throw a set of plugs and an oil change at it. Even if they're not all broke I'll have good parts on hand in the event of a future failure.
While playing around with Torque Pro this afternoon monitoring the items suggested, the car did start to puff out some significant white smoke (but it died down). I was initially very concerned as the symptoms initially onset as soon as I throttled up to pass someone on the highway, but the smoke smells like pure fuel and after some quick searching on the forums, it appears that's fairly indicative of an injector. Racingmason23, Tomc612, and FO SHO all had the exact same issue it seems. Here's to hoping it's a simple repair.
Thanks everyone for the help, I'll post up once the parts arrive and I can mess with it. I'll probably swap the FPCM first and see where that takes me, but I think injector is second on my list and my likely culprit.
Here's a
quick video of Torque Pro with the car idling while misfiring today, the smoke died down almost completely by the time I took this.
I think the best course of action is to stop screwing with it before I damage something and wait for my bits to arrive. Hopefully in time for the weekend.
Again, thanks for all the help from everyone. Definitely makes this less stressful.
