Need Help - DCS DME EGS Issues

I have been chasing issues/check engine lights on my car since I bought it at the end of December. Basically I bought a car with an idle issue, prior owner said he had his mechanic look at it and it was either the ICV, MAF, Coils, or Cam Sensor. Told me he didn't want to put money into it.

Fast forward, Idle issue ended up being a cracked valve on cylinder 2 (yes prior owner knew this but also knew enough to misdirect, expletives here for him). Replace head with a VAC Motorsports head, replaced ICV, MAF, Plugs, and the parts list could go on. At this point I have invested an additional 3+k into the car just to get it running correctly and through inspection, but it consistently throws SES. I have methodically been tackling the issues and now the remaining problems are just baffling.

My last DIS scan showed the following:
DCS5.7 - 76 DME/DDE does not fulfill torque request - DCS actively switched - no ABS control - Stop...
EGS - (145) 91 Can Torque reduction - General fault- -- - Sporadic fault - -- - Currently not present...
DME - (211) D# Idle-speed control valve, mechanical fault - Idle-speed control valve jammed open (P1500 ...

The DSC, ABS, Brake, EML lights come on after about 15 minutes of driving but reset when I turn the car off. Once the car is warm, they come on almost immediately. The check engine for the DME is sporadic and the ICV is a brand new OE part.

I am leaning towards an issue with the wiring and connectors but this is just a guess at this point. If complete parts list of what I have replaced would help let me know, I just didn't want to put it all if it wasn't needed.

Any help would be greatly appreciated!
