will do chris
and thank you all, i haven't done it because I have been overwehlm at work with a lot of work to do. this saturday i will plug the tuner in and see what happens. the car has been running normal and better with the 87 performance tune from bama. this SES light came on after 90 miles driving after i had my 85,000 mile service done at ford. the ford service folks that did my car at the time said that everything is running good before the light ever appeared, unless they missed something.
