Got some problems and Need help

My truck has run real good for a good while no problems but a few minor things. but now lately its been a pain in the a$$. Heres what it does the check engine light comes on and then the truck shifts hard and the engine sometimes stalls stalled 2 times today. Sometimes the check engine light comes on as soon as i start it up. It will also run rough and when i would let off the pedal sometimes the engine rpms drop below normal idle and the engine studders. I used my superchips and pulled these codes so what do they mean? P1280-ICP Circuit out of range low, P0603-internal ctrl mod KAM error, P0211-injector circ error cylinder 11.I just put in a new Blue CPS and TPS bout 3 months ago.
PLEASE HELP!!!! This happens everytime i drive the truck now.

I wouldn't rule out the CPS, even if it's new(er).
P0603-internal ctrl mod KAM error =
OK for now, Do you have a chip? They will cause this code, you may want to remove it.

P0211-injector circ error cylinder 11 = No listing in my book???

P1280-ICP Circuit out of range low. =
DTC P1280 indicates injector control signal circuit out of range low was detected during KOEO Self Test or during continuous diagnostic monitoring.

Possible causes:
biased ICP sensor/PCM
open ICP sensor circuit
short to SIG RTN or PWR GND on ICP sensor circuit
open in VREF circuit
Disconnect ICP sensor connector.
Key on/engine off.

Measure voltage between VREF Pin B and battery ground.
Is voltage reading 5v ±.5?
No= Repair wiring

Measure voltage between VREF Pin B and signal return Pin A.
Is voltage reading 5v ±0.5?
No= Repair wiring

The remainder of the tests require a PCM breakout box. But at this point you probably need a new ICP. IMO.

Try unplugging the ICP on the inside front of the driver's side head and see how she runs. If it runs better with it unplugged, replace the ICP.

There was a post awhile back where they were talking about the sensor on the transmission causing ruff idle. If I remember correctly they said to pull the plug, clean it, look for bent pins or spread pin sockets, and if that does not fix it replace the sensor. Try doing a search for the post.

The od light flashing and tranny shifting funny is the speed sensor on the rear diff. Pull it and clean it, see if that helps. Or just buy a new one. They are pretty cheap.
