GOT YELLOW TRACTION CONTROL SYSTEM LIGHT ON THE INSTRUMENT PANEL WITH A "MALFUNCTION INDICATOR LIGHT" BELOW THE SPEEDOMETER.ENGINE RUNNING ROUGH AT ASHLAND, VA EXIT.ENGINE WAS SHUT DOWN THEN RESTARTED WITH SAME WARNINGS AS BEFORE.APPROXIMATELY 45 MINS LATER RESTARTED TO HAVE A LOCAL CHEVROLET DEALER LOOK AT THE CAR. ON RESTART, ALL WARNINGS AND INDICATOR LIGHTS EXCEPT FOR THE "MALFUNCTION INDICATOR LIGHT" WERE OUT AND ENGINE RAN NORMALLY.DEALER GUESSED THAT IT WAS PROBABLY A "GLITCH" AND IT WAS PROBABLY OK TO DRIVE.THE 800 OR SO MILES TO SARASOTA WERE WITHOUT PROBLEMS.
