How do the plugs look? Is one a different color than the others? What I'm getting to is to determine if its one cylinder causing the problem or it jumps around. (and a compresion check, or better still a leak down check can be a good tool). With a new set of plugs, accelerate hard and , pop it into neutral at the same time you shut the key off. Pull the plugs. Compare the color, look real hard at the center electrode for the color line. The metal tip sticking up (center electode) should have a bluish ring around it half way between the tip and the electrode. You may need to use a magnifiying glass to see it. One being different will indicate a problem cylinder. Or a wet plug or one that looks burnt will indicate fuel flow problem. Repeat the test if any problem is noted and see if it moves. Fuel or compression will stay in the same cylinder, electrical "gremlins" will probably move around.
