Diagnostic for surging

Anyone got a 1,2,3..... diagnostic regimen I can follow to eliminate (i hope) the surging in my 91 9000s (non turbo)? It starts fine and idles around 11 or 1200 rpm when warm, needle steady on dash tach. Good torque off the line with poor initial accel at low revs. It picks up nicely but has a pulsing "surge" that is most pronounced around 2500 -3000. It isn't bucking or even close, just an on/off discernable hesitation. I can feel the "surge" all the way to redline but the dropoff in power is proportionally less at higher revs. Plugs were carefully gapped, IAC works though is a little sawtoothed on the edge. I definitely like the peaks in the power range surge better than the valleys. If it was another car I'd suspect the ignition wires.
Thanks for any advice////dave
