Can anyone tell me what the problem might be. I have a 98 3.8L and have black smoke coming out of the drivers side exhaust pipe. The pipe is all covered in black. Don't know what the problem could be.
I dont know about the cats..but your stang is running very rich. Does the exhaust smell like gas? Do you have a Check Engine light on? You may wish to connect a code scanner to verify the problem. There may be short term codes that havn't registered a CE light yet.
