I have a 1983 ford van with a 351 engine. The standard plug is a ASF42C. The last 2 times the van started acting up I looked at the plugs first and they had the black sutty look, which indicates a possible need for a hotter plug. Before spending money on new electrics i would rather first try a hotter plug. Please give me a suggestion on what plug would be slightly hotter so I can give that a try first.. Thanks..
