5.0L (1979-1995) MustangTechnical discussions on 5.0 Liter Mustangs within. This does not include the 5.0 from the 2011 Mustang GT. That information is in the 2005-1011 section.
I have a 1993 Mustang GT that I have just bought. I am new to the Mustang world, but I plan on being part of it for ever. Anyway my check engine light comes on just about when the engine gets to operating temp. I have a 180 deg. thermostat. Any one have any ideas. Also I want to post some sound clips of the exhaust on the site. I have BBK shorty headers, BBK offroad H pipe and Flowmaster 4o series and the pipes are cut off and turned down about 3 inches passed the mufflers. I think it sounds great.
