    Hello all, still wrestling with this issue. I took the truck to my local shop and he wasn't sure what to make of it, and he said replacing the ECU was worth a try. Unfortunately, that didn't get me anywhere. I keep hunting for bad connections, etc. and noticed something this afternoon.

    When the truck is idling high and misfiring, unplugging the MAF brings it back to normal. Idle comes back down and even the miss goes away. Now, I can't run it like that since the check engine light comes on and I lose the ability to run A/C... but it's a very consistent cause/effect when I plug and unplug that connector.

    The question is... is this indicative of a bad MAF? Would a truck with a good working MAF idle down in that situation? Replacements for these trucks sure seem hard to come by, might be impossible to find new anymore. I cleaned it with MAF-specific cleaner at the beginning of this wild goose chase, any experts know if trying to find a replacement unit is a good bet?
