TPS Voltage

[1320nut]

My 5.7L is ~.45 Volts according to TunerPro and that's why it shows my TPS % at -1.

According to this guide you should have .58 - .59 VDC

I guess what I should have said, is I can only get .88 volts at idle, didn't know what everybody else was getting?

I'm confused. Your IAC shows ~89, your TPS shows a steady .29, which one are we concerned about.

both, my idle is stuck at 950 -1000 rpms blm is at 112 running rich I can't seem to control it can't figure out why so rich? (new coolant temp switch, rotor, cap, wires, plugs, ignition control module) all I did was install a 700r4 and reseal the engine??
