HELP...SES light on/ engine running VERY rough

So I was on my way home from work and all of a sudden my truck started running very very rough, turbo spooled just fine but I had absolutely no power and my SES light came on. It was dark so I didn't notice any smoke of any kind. I don't have a code reader either. Any tips? ideas? things to check? im hoping it wont be something as costly as injectors or anyhting. its almost as if half the engine is running.

Your asking for someone to look for a needle in a hay stack... I'd see if a local auto parts store will loan you a code reader. Or maybe you can limp the truck down their. I'd also check the wiring harness for the injectors. Maybe your IDM is on its way out.

Yeah I knew when I posted this that it was more of a wild goose chase until I can get some codes. Just figured I'd see what people think but tomorrow I will see about getting a code reader to further diagnose this issue

I agree though, check the connection/s at the UVCH.

So me and a friend got the driver side valve cover off after some beer, tobacco, sweat and tears and find that the harness seems to be ok. the only problem with the connections is that the left side of the connector was not completely seated. I pushed it back into place but there was no snap and the clips aren't broken so I really don't think that was the issue. I guess I will try to get to the passenger side tomorrow night if I have time. If anyone has any ideas of something to look for while I got the cover off it would be appreciated. It didn't throw any codes and my HPOP is good and full of oil. If the ICP is bad how can I tell? Thanks in advance ya'll... I'm hoping its not an injector...

Pull the connector off the icp and start the truck… is there any change in condition? If the icp unpluged, the computer just chooses a defualt number allowing the truck to still run. You could also use a volt meter and probe one of the wires and record the readings. If you get .82 or so at idle then it's okay.
