k well the olds is missfiring so i need a wire diagram. also when i was trying to regap the old plugs i dont think it did anything but mess them up. ik checked how far out of wack they were and it was like 0.080 or 0.090 is what they were when i took them out off the engine. now i put them to the 0.060 gap and well the cr is running horrible WTF. so maybe wires are crossed but anyone know what wires and front and back of engine are labeled as i dont have a book
