Ok so I have a 95 rr county lwb 4.2l v8 and I'm having a recurring misfire issue. Basically to start out about 4 to 5 months ago I went out for a drive and couldn't even accelerate because it starting misfiring so bad. Come to find out the distributor cap had corrosion in one of the connections and I cleaned it off it didn't go away so I ordered a new one and problem solved. Well now about 2 weeks ago it came back I checked the distributor cap.. no corrosion so I pulled the spark plugs (which only had 700 miles) and they were black cleaned them with a wire brush and checked the gap everything was good and it fixed the issue for about 2 days then it came back worse than before. So I went and bought a new set of spark plugs and it fixed it again. Didn't come back until yesterday now it's back again but not as bad as before just slight here and there and sometimes it does it worse on cool damp mornings. I'm out of ideas. the spark plug wires only have about 2k on them.
