1990 Chevrolet Cavalier Z24 mileage: 226,000. I am currently changing my spark plug wires and have a problem. My 1990-1994 Chilton's manual does not match my old 1987-1991 manual that I threw out. My old manual showed that the spark plugs on the front of the engine were ordered 5-2-3 (left-to-right) and 6-1-4 in back (left-to-right). The new manual shows 5-3-1 in front and 6-4-2 in back. Please let me know which is correct? Dave
