7mgte stumble HELP

ccguy · 11-19-2012, 03:42 AM

there never was a intank pump. the truck is a 1980 so there was just a draw tube that went down into the bottom of the tank. there was a mechanical fuel pump on the old motor. i am only running 1 pump at a time. the second one was just for a test.
i am just running the cor.
i have swapped out the afm and no difference. i think i am going to run new wires from the afm to the ece and see it that changes things like it did when i rewired the tps (a previous thread).
3" exhaust from the turbo back, no cat, everything else is stock.

it acted the same with the .028 gap as it did the .032 gap.
thanks for helping me troubleshoot this
