ENGINE and CHECK ENGINE lights on... Heres the codes

KOEO:
31- PFE or EVP circuit has intermittently failed below minimum voltage of 0.24 volts.

KOER:
44- Thermactor Air Injection system inoperative (Right side). Not a threat because its all been removed. (me thinks i did it right)
31-PFE or EVP circuit below minimum voltage of 0.24 volts.

The EGR wires were cut off accidently and then i cut them flush and taped them off because the EGR isnt on it yet. Im working on that. Would any of these codes throw the ENGINE or CHECK ENGINE lights? Is there a certain number of codes the computer will give you at a time? Those were the only codes i got. When thses are fixed, will more show up?

Also, I left off the + battery cable last night, so the PCM had time to reset itself.

Engine light is oil pressure but I believe you said you already installed a mechanical gauge so that's should not be an issue.

The EGR will set the CE light and it sounds like you have this removed, that accounts for these 2 things.

The oil pressure is at like 27psi at idle and 55-60 when accelerating. is that about normal?

Would it be okay to drive this truck a 160 mi round trip at 55-60mph? Ive driven roughly 50 miles since the motor was installed. I have a funeral to go to and this is really my only way to get there....
