i should have been more clear, all the plugs were black, but when i bought the car the 2 back ones on the pass side were not hitting. i cleaned them, drove the car to blow the cobb webs out, then watched it idle for a few minutes. slowly the vacume would come down, exhaust get rich, and then it would finally die. one day ill drive it, runs good all day, idles good. then the next day, first stop i come too it will start to load up.
