Surges while crusing with lots of codes

[Stroker210]

This is a friends truck: 2001, F-350, DRW with a 6 speed manual behind the 7.3L powerstroke, he is running the ford severe duty ais and a 4" turbo back exhaust. Hooked up AutoEnginuity to it and pulled the following codes: P1280, P0122, P0472, P0237, P0238, P1690, P0380, P0231, P0475, P0603, P1287, P1139, P0640. I am a little stumped as to what it is and with the list of codes that long it seems like everything that can go wrong is going wrong but it runs real good unless you are trying to keep a steady speed about 63-65.

tell us what the codes' represent, and we'll go from there...

Alright, I've been busy the last few days so here are the listing of the codes meanings:
P1280: ICP low, P0122: throttle position circuit A low, P0427:exhaust pressure sensor low, P0237: turbocharger boost sensor a circuit low, P0238: turbocharger boost sensor a circuit high, P1690: wastegate solenoid circuit, P0380: Glow plug/ heater circuit a, P0231: fuel pump secondary circuit low, P0475: exhaust pressure control valve, P0603: internal control module keep alive memory error, P1282: injector control pressure higher than desired(engine running), P1139: water in fuel inicator circuit, P0640: intake air heater control circuit. That took entirely way too long to find but here it is.

Clear the codes, then run it, and scan again. A lot may be left over stored codes.

The codes were scanned not long before by myself about a month ago. I cleared them then, the one I know is a repeat is the exhaust back pressure control valve because he has turned his EBPV into an exhaust brake but he has wired it to allow it to continue normal operation as well.

inspect ICP for oil in plug. Remove the EBP sensor, inspect it and clean the tube.

Remove the TPS plug and clean it. too.

Checked the ICP sensor today- no oil in the plug. The EBP at idle is 15.7 psi the MAP is at 14.7 and the BARO is at 14.8. Going to check the sensor and tube tonight since we have some time to work on it.
