jdl 12/22/2011How long since a tune-up? Any applicable trouble codes? Does it restart quickly after it stalls? On a clear day, start the vehicle, raise the hood, use spray bottle with water, spray the plug wires, any effect.
Raise the hood in the dark, engine running, does it look like the great northern lights, can you see fire jumping?
