1211 is DC/PSI over/under desired If I remember.
Not a big one.
Means you got on the go pedal a bit and the hpop cannot keep up.

P0344-CMP Camshaft pos sensor ckt intermittent Incorrect number of CMP transition counts Harness routing, charging ckt, sensor, int ckt, improper gap

P0470-EBP Exhst press sensor ckt malfnct (96 MY) No-start or crank mode Biased sensor, open signal return

P1211-IPR ICP pressure above/below desired Continuous and KOER on-demand test IPR valve failed, stuck, or shorted to ground

Sounds like you might need to change the CPS and clear the codes and see if they come back.

0470 is probably because your ebpv is unplugged

1211 could be like william said, I used to get that code before my hpop change

0344, cam sensor or check over the wiring close too.

I think I'm somewhat right here...

If your ebpv is unplugged, that'll set the code, and you don't need the tube at all. It can be removed and plugged at the manifold if you wish ( if your ebpv is unplugged or deleted). Or just leave it. I didn't know this and ended up overnighting a new tube as I bleeped my threads up and neeeded the truck. Found out later, after 50 bucks of air freight...
