1987 Grand Marquis LS
Hello, i have a 1987 marquis, been having some electrical problems. I dont know if i need a new distributor, CPU, wiring harness or just a better battery. Ive replaced the alternator and sparkplugs/wires, but i am still having trouble. I know all of the plugs are not firing, and i am losing power some how. I have a sound system, and i can't upgrade the alternator with out doing some custom wiring due to the plug on the alternator. I have alot of questions and need some answers. Please contact me and help me out.
