Hi all. I got a 1994 LX Sport. It was my Mom's. has 62,000 miles on it. And yesterday it started running rough when I pulled to a stop light. Sounds like it's missing on a cylinder. Turn around and limp it home, it's detonating under load. Sounds like a diesel. So checked coolant after it cooled. plenty there. Was going to pull the plugs and replace them, the wires, rotor and cap. Only to find nobody can get the cap and rotor. I was at AutoZone, Advanced Auto, NAPA, online at Rock Auto and even Fords site. Everyone has it listed for the 1.8L but zero for the 1.9L. Any idea where I can these?
