pedal sensitivity

[noncom23]

2006, 4.4, 13500 mi. No mods. v.23 tranny upgrade. In the am on first
start up, the pedal is so sensitive it runs off with barely a touch.
As it warms up, it takes more foot pressure for the same result.

Is there a mechanical reason for this ie; vacuum line
MAF
ECU, etc...?

Same thing with mine.

You engine is idling slightly faster when you fire it up in the am. As it warms up, the idle dpeed drops. Nothing wrong with your ride!
