P0235- turbo boost sensor A Circuit error- not sure


P1280- ICP Circuit Out of range low- unplug the sensor and look for oil in the plug

P0122- Throttle Pos Sensor/Switch A Circuit Low Input- not sure but these two might have something to do with you tran acting up
P0221- Throttle Pos Sensor/Switch B Range/Perf

That slip your feeling could be the go pedal cutting out for a split second

With a good mutimeter you can test the TPS

Leave TPS plugged in and key in on position
Set meter to volts
Put hot lead in the middle wire on the TPS plug from the back side of the plug where the wires go in
Ground to battery
Then slowly push the go pedal down watching the volts to see if you have a dead spot in the TPS

Isn't a slip an RPM increase & a flat spot in the TPS an RPM decrease ( more often described as a stumble)?.

Yes it Rick but I had a TPS issue that had me all over the place. Sometimes it would feel like a slip and other felts like a miss but you never knew when it would happen and when it did it was do fast that you really didn't know what to make of it. So that's why I said check the TPS

Sorry about that ,, An RPM increase from a bad TPS is a new one on me ...

To the OP , If you have cruise control , you can try driving it with that to rule out the TPS as well...

If you can , run the truck till you can use the cruise control. Run the speed up & down with the steering wheel control. Look for flat spots or RPM changes .

I'll leave it to Ford pride from here ...
