My thanks to this news group and several websites that decribe the
main relay problem. I had an intermittent problem with flashing
sports light and check engine light for 5 years. It was getting bad
enough that I was going to donate the car. Dealer wanted to
put in a new transmission. A mechanic said he replaced the main
rely. I finally took out the main relay myself and found bad solder
joints exactly as pictured on several web sites. Bought a new one
for $40 (too timid to try fixing solder myself). Problem is solved.

Thanks again.
