SC Bucking... Still

So my 89 SC keeps "sputtering" when under 1 1/2k RPM. If you put it in any gear while it's at a low RPM it'll buck and sputter violently.

So far I've changed the alternator and new plugs/wires. I had a compression check done and all of the cylinders are fine.

Any suggestions?


Thanks.
 
i would pull plugs first to see if i could tell which cylinder was missing and check wires make sure none got against exhaust or check for dirty injector

Check your cats, Mine bucked vilently when they went bad. If its happening at high rpms (under boost), spray the air bypass (behind the SC) with WD40. Good luck
