.....power surges.....
....94 coupe, 100k miles, with fuel system recently overhauled, new dynaspark......runs great, acceleration, deceleration, idle, starts great.....i refuel only after using the top quarter or half a tank.......except every now and then, i detect some surging in power. tach does not register it, so i am wondering what it is. are there any ideas from anyone?

ideas
Fuel pump weak, fuel filter clogged, fuel pressure not steady or high enough, cat converter historic, grounding ignition wire, goofy ECM or chip. sensor malfunction, tps not set correctly or malfunctioning, intermittent vacuum leak (at manifold?), just to name a few.
