Having a problem with my 01 Camaro. Only under a load at WOT above 4500 rpm the car acts like it's going above 6500 and cuts fuel. Just what it seams like.
I also noticed that number 8 cylinder plug shows signs of detonation.
Spark is good, fuel pressure is good, injectors are good, wideband is reading good.
New plugs helped and a few crankshaft relearns also helped. Not a greatly but did help.
At this point I'm thinking wiring/ground could be the culprit.

How do you know that the injectors are good?

Is your "good" fuel pressure at the point of the problem,
or on the driveway?

Logging cylinder mode misfires would be useful but
this only extends to mid RPM. Maybe there are early
signs anyway. Swap parts from any cylinder that
stands out, in an orderly way, and see what happens.

All injectors have been tested and cleaned.
Pressure is good at idle and under load at WOT.
