Intermittent Rough, need troubleshooting help
My ride:
1994 Ford 350 XLT dully 7.3 turbo. 180k miles
I've done a lot of reading on this "intermittent rough running idle problem" and I need to troubleshoot to see if I need to open my valve covers.
I found this thread: https://www.ford-trucks.com/forums/8...ck-shakes.html
The thing is my truck has 2 - 5 prong connectors on each valve cover and I'd like some help ohm-ing this out seeing if I have an open or short some where.
I also found this:
Seems like I don't have a common ground....
Can someone help me with what steps to take on finding out if I have a bad injector, glow plug, and or open.
Thanks for your time!
Does anyone else recommend any further troubleshooting before I just bring it to a shop?
I will add, temperatures been dropping at night past few days, last night it probly got to ~35F, when starting it this morning it was smoking pretty good....once the engine is warmed up enough smoke is mostly gone.
Thanks.

Remove connecter at valve cover and measure from outer pin to gnd.
How many mile? mine smokes a lot when cold but I know its injector Armature clearance that is retarding my timing and possibly the oil return isn't big enough on the injector making cold starts harder.
I just bought this shim kit to install next week along with new GPs and GPR

I went to check the glow plug, pull the connector off the passenger bank front and it's covered in oil and the connector looks burnt....
this is the forward connector front:
and this is the passenger rear connector, it's got the pin but peace of the corrector broke....
Drivers front, Connector looks fine but covered in oil....
Here is another kind of side subject but I was doing some reading and wondering if my o rings for injectors were going, so I dumped the bi-pass from the fuel filter bowl and collected it......Idk what to say about it.....it really has no smell and kinda gel like......anything to be concerned with?
So what is a corrective action here? Do I have to buy a whole new harness? Where to buy? I'll get some contact cleaner and still try to ohm out the plugs... thanks so far on the right track!
Also ordered 8 new glow plugs, Brand: Motorcraft.........motorcraft is a good brand right?
I'll keep everyone up-to-date.

for some reason I decided to pull pins out of the valve cover harness and found one pin had broken off inside and would break contact sometimes
Bought a new plug and replaced the wire and pin and was fine
