problem: engine misfires at WOT and won't make boost, when I took the oil filler cap of there was white smoke comming out of it and there's also white smoke comming out of my exhaust.

Did a compression test on a cold engine (because it would'nt start yesterday):
front rotor : 100-105 psi , rear rotor : 105-110 psi looks like a healty engine.

Tps was broken so I put another one in but when i adjusted the thottle body to have the correct impedance @ idle, the voltage on the ecu where way of and the engine wouldn't start, so i adjusted the tps so the voltages where @ 0.8 and 1V and the engine started but rpm was @ 1800.

Has anyone had this problem before?
