Yesterday I went to clean around the engine bay so I removed the cap off the distributer, just the black plastic piece on top. I then removed one at a time and cleaned it, and put them back on as i took them off. I'm almost positive I did it correctly, but does anyone know where I can find a diagram of the correct plug setup because my car doesn't feel strong today. If one or two was switched it would run poorly correct? And that piece of plastic has nothing to do with it right? I'm trying to figure out why it isnt pulling at all today. It is very very humid and hot out, so maybe thats it also.
