My service light keeps coming on.......

[dj norecords]

I have a 1987 T-Bird LX with a 5.0 V8 and recently the service engine light, located right below the speedometer on the electronic dash has been coming on. It's quite strange. When I turn on the engine it lights up, but when I keep driving for about 20 minutes, it turns off, and then when I stop the car and turn the engine back on again, the service light comes right back on. My Dad says that the light is just a warning light that suggests servicing the engine every couple thousand miles, and that it's nothing to worry about, since we just had the T-Bird serviced from top to bottom (from oil to engine, to brakes, etc.) Is it really something that I should be worried about? Anyone know anything about this? Any suggestions as to the mystery light would be a great help. Thanks.

Your EEC-IV has a message for you! Thats why the light persist. You can get a code reader for around $30.00 at your local auto parts store, Wal-Mart, Target etc. They usually come with a book that explains how to hook the reader up, run the codes and then a list of what code means what. There is a way to retrive the codes with a jumper wire that is described on the NATO board by Jeff Korn - although it is for a Turbo Coupe - the process is the exact same for your 5.0
