"Only happens at WOT" You have a manual transmission. Are you sure you are not bouncing off of the REV limiter?

Hi
issue was solved by replacing all the spark plugs.
and by the way was happening also at 2k rpm, so could not be the limiter.

How many miles are on the car? If it's low miles it's interesting that it'd need plugs/wires.

Did you check the gap on the plugs that were causing an issue? I wonder if they weren't gapped correctly. I bought some new AC Delco plugs for my truck and almost all of them needed the gap set. I thought they were supposed to be pre-gapped but they definitely were way out of whack.

All of them were correctly gapped, also the color and the electrode were looking fine. The issue was most likely internal.
