I got the injectors cleaned and placed back into the truck, no change. I am misfiring the most on 1-4, with a few misfires on 5 and 7, and very few on 6 and 8. I have 12 volts on pink, and there is about .7 ohms of resistance on the ground wire on 7 of them, the 8th one if 1.7 ohms. Noid light flashed on all 8. Still have the p0200 and p0300 codes with a lean condition on bank 1. One thing I noted is that when I unplug the MAF the truck seems to be running better, although it seems that the MAF being disconnected means that the misfire counter on EFI does not work, however both O2 sensors are around 800-900 mv. I'm using the original MAF. I'm pretty much out of ideas so any ideas are appreciated.
