1997 Mercury Cougar ProblemsEngine problem
When engine gets hot and you start it it misfires for about 1 minute and then smooths out. Cold start ups run smooth. I need a fix for this problem!
The battery light may illuminate on the instrument panel because the alternator wire harness connector is damaged. A new connector kit is available and should be installed to correct this concern.
White smoke coming from the exhaust could indicate that a head gasket has blown or there is a cracked cylinder head. Our technicians tell us that removal and inspection of the cylinder heads will be required to confirm a crack is present.
