fuel pedal problems
ok so a year ago my factory fuel pedal went south, went to parts store and got new one. now every 2 months it gets to going out, surging at highway speeds, if i let off the fuel the check engine light comes on and i tap the pedal 4 or 5 times then it works again, replaced 3x in the past year.
are all the aftermarket pedals junk or is their something else going on, truck is a 2002 F250 7.3psd auto with 415,000 miles

If the IVS and the TPS become out of synchronization a code will set and you loose acceleration.
Since you've replaced so many. I would suspect the wiring or connection. Try some Elec. Contact Cleaner on the Plugs before replacing again.
If you have a Scan Tool, you can compare the two PID's and see which one is (IVS/TPS) suspect for further troubleshooting.
You can monitor each switch by using a DVOM to compare the movement / resistance using (Ω).
It's also possible the connection at the PCM is dirty/corroded and requires cleaning.

You have the 9-Pin Connector, but still two Sensors in the pedal. Same set up, just one plug + APCM 4 wire accessory wire (which were separate in early models).

You just have one plug in lieu of two separate plugs (5 Wires vs 2/3).
Again, if you have a Scan Tool, you can compare the two PID's and see if it is in fact the pedal.
