2 different problems!

[semperfi3533]

I was driving for about 10-15 miles with absolutely no problems, then my service engine light flashed on for just a few seconds during this time I lost all throttle response, I had my foot on the gas and it was practically idling, the light went off and my throttle response went back to normal, 2-3 miles later I noticed it started to jerk around a little, nothing serious, it seemed like the trans was confused for what gear to go into.

* My 4x4 light has been on for the past couple days, and it's in 2 wheel drive (my father-in-law said something about a "plunger" getting stuck, and it reads 4x4 even thou it's not.)

I don't know if that issue could have anything to do with this, but I thought I would mention it.

My truck is a 2001 F350 (not a dully)

There are 2 issues that might apply here.

One is that the TPS (Throttle Position Sensor), located at the top of the pedal, has been problematic in some versions.

Two, the OD (Over Drive) switch, located at the end of the Automatic Shifter Lever, wires chafe through and short to ground causing the PCM to get confused.

Those chafed wires are SO Common (and A "Free Fix") that I would take a look there first.
