I have a suggestion for you, it's called ENGLISH. Speak it please son.OTB Race Team said:get new plugs and if something if it does it agina then somethigs wrong.
Anyways to answer the question: I think your plugs have what is called a lead glaze. If the computer said nothing is wrong with your car then your problem is probably how you drive it. If you excessively idol it then take off F&F style, this will cause your plugs to have a yellow or green color to them. Only other cause for that color is an incorrect carburetor setting.
