Thanks Moby, I swear I have half a brain, or approximately thereof, but seriously I question myself a bit because this is sure taking forever.
Right now I have one ground to block (and only 10g I think), and 2 "good" grounds from the battery to the frame. I will add at least one more to the block, some of my accessory grounds are coming from wiring to the battery @ the framerail.
I am going to check these few things mentioned, and if that doesn't do the trick, I'm going back to step 1 and check everything again, trusting nothing basically. If that doesn't do it still, then I have to make the assumption, diz/ecu and/or injectors are at fault, then I can troubleshoot those as well. I'll try checking the injector resistance too.
