Im stumped on this bog
Problem is this:
Car runs great except at over about 50% throttle. Then it falls on its face.
Replaced the TPS, Plugs and Wires as per another thread describing the same problems. I suspeced cross arcing at high loads thus misfiring but that was not it.
The car makes full boost and is fast at part throttle, it has no known vacuum leaks and FPR is new. AFM was replaced with a known good one.
The bog seems to be throttle position dependant, if I go past a threash hold point it bogs.
Any sugestions or similar problems?
Possibly knock? I bought a new knock sensor but have not installed it yet. I'm running 94 octaine gas and have had a few tanks in it with no gain.

Found it!!!!!!
Knock sensor wires were badly corroded behind the connector, not on the sensor side.
I replaced the plug and the sensor (since I ordered a new one anyway). We will see if that fixes it. But the fact that it was all green and only took a light tug to break the wires may be a great indicator that it was problematic.
