WOT engine stumble ??

Was running fine after a nice tune-up, month later a stumble starts when I hit it. Fuel pump tests fine, fuel filter if clean, intake elbow is good..... any ideas?


Thx

Might be plug wires, had a problem at high rpm WOT acceleration on my Z last year, replaced plug wires even though they were only 10k miles old and showed no sign of arching at night.
