anyway, my dad has a 96 k1500 and its got the 350 vortec. a few years ago, it backfired and hasnt run right since. hes replaced the longblock, injectors, map sensor, tps, plug wires, plugs, cam positioning sensor, knock sensor, iat sensor, egr valve, pcv valve, trans, and o2 sensors. and it still runs like crap. it has a rough idle, accelerates with a lot of stuttering then cleans out at high RPMs. like its choking itself out all of the time. hes had it to a few shops and they have nothing to say... any suggestions or has anyone run into this before? we're thinking maybe computer? it had a ses light on until i ran a can of seafoam through it.

again, sorry its not an f bod, but i gotta figure this one out

my 90 gmc did something like that and we took apart the TB and under the injectors it was totally clogged with dirt ??????????? i replaced it with ajunk yard unit and it ran great again <<<< maybe it something like that guessing - jz
