Bad Misfire at WOT

[sleepydsm]

Tp respond to everyone:

I have cleaned my injectors once, last year. I may have to do it again. I had black goo on mine, 120 seconds in gasoline and they are good.

The plug wires are OEM replacement NGK, probably have 10,000 on them.

To Alpha D. I have a nearly brand new OEM knock sensor. And my ignition timing is correct.

I got a box of plugs I'll toss in and see what happens.
