No, it wasn't running fine before I changed them. That's the whole reason I did it. I had brought it in to the dealership because it was acting funny when I got on the throttle. They said I had a fouled plug and wire. Now the problem is almost reversed, it's fine when I'm on the throttle, but the engine jumps with it's idling. The plugs are still the stock ones cuz I don't have an air compressor and there's now way those things are budging without one. I guess it wouldn't hurt to double-check one more time (quadruple-check at this point)Originally Posted by Ron-E-Babe
