Problem started when cruising home. Stopped at gate, when I hit the gas it stalled and died. Got it cranked again and if I slowly accelerate it would run fine, Too sharp on the throttle it cuts out and then can run when I let off. Idles fine, runs pretty good. Just cant step on it. I checked voltage of wire to TPS it was 3.3 V. I went ahead and stripped back the white tape a good ways didn't see any major rubs, Found a few spots exposed on white and green wire. I put black tape wiggled around cant seem to make it cut out. Could it be weak fuel pressure some how? I got new wires for fuel injectors and replaced one, but both cylinders are firing so just spending money before i figured out it was TPS fault and not injectors. One check engine code 51 4 stands for low voltage TPS.
