Damned diesel mechanics, LOL. Welcome by the way. Start with the simple stuff without spending a ton of money...... sounds to me like it's idling and running OK, just you suspect it's rich?? Clarify if different...
That old girl should have new plugs. Take a look at the old ones, the blacker one is the richer one, if there's a richer one. While there, remove (unscrew and pull) the spark plug adapters off the wires, trim off 1/4", spread the strands and reinstall the adapters... nice fresh connections.
Remove vacuum hose from MAP sensor, the black thing on top of the left half of your throttle bodies... remove the two screws and the electrical connector... ensure the hose is clear of any build-up crud and the plastic port itself.... don't go poking too deep, don't want to damage the diaphram. All clear, reassemble.
Siphon out the old fuel, put in fresh with a couple ounces of Seafoam. Fire it up now and go for a ride..... let us know if you still have a problem when at operating temp and idling.........
If you're a mechanic you can do all the service yourself..... yep, get a service manual... there are information threads about valve checks, etc.
Save your money on coils and 02 sensor... I don't think you'll need to go there. Coils especially, if it's running, you're good. None of that other stuff the Yammy guy is going to do is going to solve a rich problem. Best put your location in your profile, maybe I can direct you to a tech day near you.
Keep yer stick on the ice....
