The cold has made the issue a little worse, but luckily I got some good data to go off of.
When the truck started misfiring STFT went up to +15. Rev the engine a couple of times and it clears up. Rev it some more and it can come back. As the RPMs are going up it can still misfire but if you blip it right it goes away.
This is starting to sound like an injector. I wished I had an Oscope so I could see the voltage waveform. I guess I'll try to do a cylinder 1 to 4 swap this weekend.
