In an effort to boost the MPG on my Dakota, decided to put plugs and plug wires on it this morning.

Found this little gem when I pulled the cap off.......





Now, mind you, it started fine and seem to run fine. No obvious miss or real roughness.

Put all my parts on, WOW!!! What a difference! It was almost buttery smooth and I now had a traction problem taking off from a dead stop (roads are damp, wasn't doggin' it).

Got home, turned it off. Cleaned up my work area, went to leave again, and, its running worse than poo......stalling, running REAL rough. Huh? When I parked it, it was fine. Doing nothing but letting it sit and restarting it, it runs terrible. Its bad enough I can't drive it.

I've double checked my work. Double checked the cap, can't find any issues.

I'm at a loss. Ideas?
