1982 engine hesitation
i recently purchased an 82 and took it to the shop to do a full tune up. when i got the car back the car ran great. i took the car for a cruise today and felt the car hesitating. it felt just like when i purchased the car. i changed the fuel filter but same problem persisted. i then took the spark plugs out to inspect them and i noticed that one of them was really really black. i cleaned it and now the car runs great again. what would cause the spark plug to get black?

Don't know about yours but mine did that too. It turned out to be a worn lobe on the camshaft.I'm not saying yours is the same, it could be anything from a plug wire not firing right, a leaking valve seal, or worn rings on that cylinder.
I wouldn't think it is a fuel related problem because you would have more than 1 plug fouling.
let us know how it turns out.

Re: 1982 engine hesitation (Desertdawg)
Did the problem persist or did it go away when the engine got warm? fouled plugs are not that uncommon, especially when you start the engine and shut it down before warming up. Do that a couple of times and you'll have some nice fouled plugs in no time.
If the problem persists, check the lugwire for that one cable, check arcing and resistance. Also check electrode gap on the plug. It could be that the one cylinder isn't firing properly. If all is fine, it could be a fuel distribution problem called crossfire injection ;) There's no way a single cylinder runs very rich due to fuel metering problems. It might be a cam related problem, these cams are not very good indeed.

Re: 1982 engine hesitation (mannymen)
The problem persists even after the car warms up. it even gets worse the more i drive the car. yesterday was the worse. i guess it got to a point where the plug was not igniting at all. i will definately check the ignition system first before dealing with the fuel system. i have one question. what is the Lugwire?

Re: 1982 engine hesitation (mannymen)
Ohh! makes sense. i don't believe i didn't figure it out. by the way, what is the best way to test the spark/juice going to that plug? is there a special tool? i was thinking of swapping plug cables with the plug next to it, of course swapping the end on the distributor cap as well. if the other plug starts to foul, the cable is the culprit. this seams highly unlikely to be the problem since the all the plug wires are new. what do you recommend?

Re: 1982 engine hesitation (mannymen)
Try changing plugs with another cylinder as well as plugwires with another cylinder.If the same cylinder is still fouling the plug,you may need to do a compression test on all your cylinders,to draw a comparison.
It's trial & error I'm afraid.
