backfires when reved. It has barely any power and
once it hits about 3k rpm it looses all power and

Do a tune up. Fix all the possibility s first. If it still acts up,, it maybe the throttle body sensor and or power transfer unit which is under the coils I had to replace those and mine worked fine. But this doesn't mean mine symptoms are yours. But it's a start ...hope this helps
