99 1500 2wd, throttle issue
Alright, time to explain. While driving, pedal half way truck runs amazing. If I push the pedal to the floor, truck downshifts and at 3k it bogs out and doesn't want to accelerate.
I did a compression check on all cylinders, 150psi.
I replaced the cap and rotor, wires and plugs.
I had a cylinder 6 misfire, but it has gone since replacing the cap.
I was thinking the tps sensor or fuel injectors, any suggestions?

It is an automatic, in neutral it revs fine.. No hesitation at all.
It seems to happen from 2nd and up, even with overdrive off.. Even tried it in low, still the same.
I read somewhere that bank 1 o2 sensor can cause it? Or the pre-cat sensor?
As for the transmission that was replaced about 3000 miles ago and was fully rebuilt.

I'm jumping on the clogged cat/exhaust restriction band wagon. Does the check engine light flash off and on when it bogs? You can hook up a vacuum gauge to intake, then slowly bring rpm's up to 2500 plus. Normal vac reading should be around 17 or 18in with a steady needle. If the needle falls while increasing rpm,s, then she is clogged.
