This turned out to be the spark plugs and wires. I took it to the dealer and they said this was due to the wires. Is it typical to replace them at such low mileage (40,000), and not much wear and tear? I thought that they should be good for 100,000 miles, according to Ford's claim on tune ups. This turned out to be expensive too...$550! I'm going to look into this to see if they ripped me off!
I have a 95 Contour with the Duratech V6, manual transmission. Last week the car started to "sputter" and run rough. The check engine light comes on occasionally when driving. It loses power when accelerating too. There is a different smell coming from the exhaust. My friend thinks that it might be the catalytic converter. Any help/info would be appreciated!
