7mgte stumble HELP

[ccguy]

well i pulled the motor harness and checked every wire. i found the shielded o2 wire was grounding to the inner wire. so i fixed that. everything else checked out good. so shit.
i unplugged the knock sensors at the ecu and it threw the code. and made no difference. i already did the rewire and that fixed the original wiring cel code.
as of today i started it and it was hard to get to fire. even ran crappier than normal. it still backfire POPs into the intake manifold when it is doing the hesitation.
also i unplugged the oil pressure wire to the ecu and it made no difference in how it ran. also my oil pressure is reading high or it at idle (so i might have a new oil pump in my future if i dont light this thing on fire only to piss on it to put it out

it kind of sounds like my shit and he replaced the afm with a maft and gm meter.......
i think i am going to try a new afm and see if that works???? i have tried 2 other used ones and to no avail.

could i go the maft rout or should i maybe go for the maft-pro???? i think my main problem is the tccs system being retarded somewhere in the mix.
the maft pro would basically replace my tccs ecu correct???

thanks for all the input.
