Angry s4 engine runs really crappy whats the issue?

well i just pulled out of the speedway gas station from getting a pack of smokes, went to dart out into traffic and i bottomed out my car, (its slammed on tein coilovers) then i try to accelerate and my cars seems to have lost most power on the low end, bogs harder than usual around the 3800-4k mark. and now after 4k my exhaust has a higher pitch than normal and has a lose of power on the top side, my intake did end up falling off the front of the afm but never came off the tb, now my intake is all good but car is still running like crap and cant figure it out. please rx7 gurus i need your help

pinch a fuel line? Check the wiring to the sensors on the trans also, they sometimes hang pretty low.
