Check engine light came on and engine was running rough.
The CEL went off and the engine ran great. Next day CEL on startup the problem comes and goes.
The EGT was about 800 F when I was driving about 20 MPH. No boost pressure.
Question is where do you connect the scan tool to check the codes on 95 PSD?
Go to an advance auto store or whatever you have near and get your CEL scanned. You connect the scan tool near the passenger side of the vehicle, inside the cab, near the bottom of the dash.
Sounds like maybe a burnt injector wire harness maybe unplug the injector harnesses on the valve cover gaskets and take a look to see if any of them are burnt you will smell it if it is bad another indicator is oil inside the plug end when you unplug it .

I checked the harnesses and 2 of them have oil in them. I will pull the valve covers off and check. Thanks

I know my truck is a little newer but that sounds like the same thing my truck was doing it was the plug under the valve cover pan was comeing unpluged i slid it back on and its been running fine
Did you find the cause ? My truck started doing the same thing today .Just idling picking up hay bales,daugther driving. Engine died,she restarted it.It ran very rough and CEL came on.All gauges fine . It cleared up,then did it again. Feels like it's starving for fuel,no power. I'll check my wires.CPS is about 2 weeks old.
Thanks but that was WALJON! Nice job gentlemen. Will, good luck with the repair. You know where to come if you have trouble
Correction….. WALJON, Thanks’ for your hint on the oil in the wire connection. It pointed me to the right side valve gasket.
Thanks to all that replied to the help me out.
I have the new gasket and valve cover harness installed and tested. Ran out of daylight to get all the bolts into the valve cover.
