My 1993 Mercury Sable has been running rough since July when I would lift up on the wiring bundle it would run fine for a few days then do it agan I removed all the tape and split loom from the bundle and separated all the fires that where fused together I had to lay across the engine to get to it. I worked on it for days but still had to go places even with it running bad one day I sneezed and I got a pain in my ribs that lasted for days last week I just made it into my drive way before it died and never started again had it towed to my friends shop and the diagnosis was not good I melted the Catalytic converters I have had the car since 2005 and have had to do a lot of major repairs Head gaskets, power steering pump, Rack and pinion, Transmission air conditioning the paint is all oxidized and its in need of new tires. Daddy wolf sad!
