Have you scanned for codes? I would do that first.

Dead pedal is caused by 2 things...
1. APPS sensor which always throws a code! (P0121, P0122 or P0123)
2. Dieing VP44 which might or might not throw codes...
If you adjust a wore out APPS you might find the voltage unstable and you might have the wrong start on the idle validation switches (2 of them!)

As requested by some, here are pictures of an APPS adjustment:
First Off, this is the APPS. The black cover in the center of the picture
This is what it looks like with the black cover removed. It is held on with two plastic rivets. One on the front hiding behind the radiator hose, and the other is on top.
With the air box removed, the PCM is visible
After squeezing the back half of the connector, the connector cover is removed. I used half a paper clip to back probe the wire and take my reading.
This is my original voltage reading, as said in the instructions, I wrote that number down.
After removing the 6 - 10mm head bolts and turning the APPS, here is the sticker with the specification for voltage.
I adjusted the APPS until the voltage at the wire matched the sticker voltage. I only loosened each of the two Torx20 head screws about 3/4 of a turn.
