I got a 1998 GMC Sierra 1500 5.7 vortex, 4l60e true duals exhaust, but I can’t figure out how to do the o2 sensors, I would much rather bypass them if possible, cause it says there supposed to have 4 o2 sensors, but I can only find the ones for the 2 at the top, my motor just revs up and down at 30, but past 30 runs great till I drop back down to 30 again, and it spits and spudders when I go from dead stop to up hill, but I know there nothing wrong with Tranny, got it up to 120 last night no problem, got mad at and wanted to blow it, done bought 3 transmissions for it
