Just wondering...I hooked up an OBDII scanner to my '04 Lightning to check out some of the parameters and one thing that caught my eye is that it shows my absolute TPS position to be at 19.2% at idle. Call me crazy, but this should be at 0% at idle. Is it safe to go by this readout to adjust down to 0% or do I need to check the voltage on it and get it as close to 0.99V as possible?

tps V (Voltage) and TPS Percentage are two different readings....


TPS V should be close to .99 as possible....

It would still run because you have your IAC (idle air control) for when the throttle blades are closed.

I'll check the voltage today when I get home from work. The truck runs great otherwise though.
