Throttle Problem?

Throttle Problem?
Hey guys, my name is Patrick. I bought my first rotary in February, 88 s4 Gxl. bought it with a cooling issue, swapped rad, no issue. Fixed. Now I don't know what to do. My car hits a wall anywhere between 2k-6k. It's really strange. It's intermittently occurring. It's like it's choking out or not getting enough fuel. The weird part is, is that it's only at full throttle. If I ease off the throttle, it's will sometimes accelerate, just slowly. Now the overall issue with the problem is not cut and dry. Its either an electrical issue or a fuel issue. I'm leaning towards electrical as it feels like its trying to flood itself when I accelerate. the car seems to not want to accelerate past 25% throttle in every gear and at any speed, but I still cant punch it as once the car gets passed its "point of less resistance in the rev range" (sorry for the weak explanation) and it falls on its face. I know my 5th and 6th ports aren't working(getting fixed sat. hopefully), but maybe fuel regulator, injectors, maf, maybe the deadly grounding issue? Idk. Stumped. Any help would be great! It's my daily( if she wants to work), so I can't keep taking things apart...
Oh. What I've tried..
Swapped coils, ran injector cleaner and seafoam through, tps adjusted, tested maf sensor, and tps while problem was occurring, read out normal.

I can see that u`ve tried to swap coils, but do u know it there is a problem with the sparkplugs or cabels? As of how i can understand ur issue, id say it might be somewhere near a ignition problem.
-Check ur cables for "white/brown" spots(lacking of words) on them. If u have high resistance in the cables , the spark might make those spots, and the ignition will jump "out" of the cabel at that place.
-Id also check out the plugs and see if they are looking normal.

Okay.. Got the throttle body off to look at, and the thermowax pipes were terrible.. Explaining my high idle. 1 pipe was rusted and clogged, the other clogged, corroded, and broken. Bad.. But I reconnected everything and cleaned the thermowax to what I could. It didn't want to start at first, but got it running, and drove it. It was doing good, and redlined it. Then I got it fully warned up... There is a belt squeaking at anything over 5k... And the problem came back... Great. Back to square one.
