Customer: replied 5 years ago.
I have not had any codes read yet. I carried the truck to a local shop and they said it just needed a tune-up. They were suppose to put the truck on a scanner but I was not there at the time. I work on my on vehicles most of the time and capable of the basic tune-up stuff. The truck has a very rich gas smell and rough idle and misfires regardless of the rpm. The two middle plugs on the driver side were dark. The rest of the plugs looked fine. I changed all of the plugs, wires, fuel filter. The truck had the distributer replaced a couple of months ago. The cap and button were replaced at that time. The truck is down on power.

i want you to replace the rotor and the distributer cap again...these caps will burn up on the inside even if they look new....i have had many caps bad new,right out of the box...also,check the fuel presssure..these must have no less than 60psi at all times...sense it seems to be running rich,,the problem could be the pressure regulator that is located under the intake manifold,,it may have a busted diaphram and be leaking fuel
