Weird dull spot.
1991 L98. I have auto X-ray, it shows nothing, no codes, New plugs(MSD), wires, coil cap(Mallory). New TPS. Car has L/T headers, exhuast, custom chip.
I can't figure it out, Full Throttle it feels fine but if you roll into the throttle or you are going 40 or up and give it 1/2 throttle it surges or misses more like a surge. Took it to a driveability guy he couldn't find anything. Had it put on the dealer computer, nothing. Any ideas? I am thinking fuel, but am really stumped at this point.

89 l98-going through the EXACT same thing. Dropped it off this morning to the local GM tech expert. Keep you posted on what he finds if it helps. I finally threw in the towel and realized it was beyond my capabilities

See it looks like an adjustable one but it looks like there is no way to adjust it, I mean I know where it is and the one on there is not the stock one but I see no way to adjust it.
