Please help I pulled the codes from my truck and it would seem as a mass connector is loose or full of water, but which one?

codes pulled are:
P2141
P0102
P0488
P0487
P2A00
P2A01
U010C
P245A

2008 2500 6.7 blu-tec Stock
it appears intermittent as it limps and at times the turbo kicks in, and then its flying unfortunatly the last time was in front of a cop.

Please need help soon!

Thanks

Warren
