ok, I have replaced plugs and checked fuel pressure. it is at 47
pounds. I sprayed carb cleaner and checked for vacumn leaks all around
including intake. I have a fresh tank of gas with seaform additive and
it still missing/jerking. It is gettting worse tho, idles fine, runs
fine, just acts up on acceleration and worse under 2000 rpm's. it doesnt jerk or miss when it is floored. I pulled each wire
off and there was a noticeable difference in the rpms each time.

any other ideas?
