I know there is another post concerning this, however I have a little different of a problem.
My rpm jump around at idle. Not like I have a vacuum hose leak, but say 50-100 rpm, and the idle is rough, plus it misses constantly. I have switched out the plugs to NGK 6097 gapped at 0.030 and only have 10k on a new motor. I am pretty sure that the coil packs are brand new as well, 10k old with the engine. I have a S-AFC tuned and I don't know what the problem is.
