So this problem is intermittent and it only seems to happen under a load. Doesn't seem to happen when I rev the engine.
ON idle the rpms will raise under turning on my high beams to 3k
or just sitting it will rev up and sometimes will settle around 1.5kor 2k
When cruising it feels like it misses here or ther but it isnot reflected in the rpm gauge.
It appeared to only happen at less than 1/2 tank of gas but does not occur when over 1/2 tank.

the second video shows how violent the stutter can be... please pardon my loose interior rattles and rap music on the second and third videos.
I was gonna do a cam swap and egr block off, but feel its a little more important to fix this before i go adding complications.
the car is a 93 2.0l mtx with the upgrades in my signature. I have redone the passenger side motor mount ground and drivers side motor mount grounds. I have a battery relocation in the trunk with decent ground as well.
I was gonna do a fuel pump hoping that would "solve" my problem. Fuel filter, cap, rotor, wires and plugs all have less than 10k miles.
