plugs were long overdue. new plugs are the same # that i took out. when i disconect wire to fuel injector on # 1 cylinder, it makes no difference in how the motor sounds. When i disconect #2, i can tell a difference in the way it sounds. there was some codes, i cleared them after replacing plugs. they were 300, 301, 305, 340, 442, 455. service engine light has been on a long time. engine light is not on now, but the motor idols a little rough and when you start to drive it, it shakes bad. i think #1 plug is not getting fire to it. i took # 1 plug out, and it was clean, #2 & 3 had some black stuff built up on them.
