Has anyone tried this throttle system recalibration on a 4.6?
From the F150 Forum:
"I had the same problem on my 08 Limited 5.4 when I bought it 2 months ago. Here's what I did to fix the problem. Turn the key to the on position but DON'T start the engine. Now press the gas peddle to the floor SLOWLY and let it come up/back as fast as you can, turn key to the off position. Now do this two more times. "
Seems that this recalibrates the Zero as they drift/slip/shift over time.
I also recently saw an ad in a magazine for something you connect in-line with (electronic) cable that connects to the gas pedal. Can't see how that would improve throttle response unless it re-scales or re-curves the voltage from the Rheostat? Initial boost in voltage, perhaps? Has anyone here tried one of these things also? I have an XCal, but it does nothing for throttle response.
