Try this. The spark plugs are under the large black rubber pieces on the top of the engine, just in front of the intake. Two of the plugs are under the black plastic rectangles (these are the distributors.) When you pull the rubber boot up you will find a 4" post that connects onto the spark plug. Needless to say you will need a spark plug socket, an 11 mm socket, a 4"-6" extension piece and a ratchet. You will only find 2 cables that look like spark plug cables on is about 4" long the other is about 12" long the other 2 plugs come directly out from under the distributors. Good luck!
