I HAVE A 94 FIREBIRD TRANSAM. THE MOTOR WILL QUIT WITH NO WARNING. THE SEVICE ENGINE SOON LIGHT DOES NOT COME ON. IT WILL USUSALLY START AFTER A FEW MINUTES AND RUN NORMALLY UNTIL IT DOES IT AGAIN. I HAVE HAD IT LOOKED AT BY SEVERAL MECHANICS AND THEY DO NOT KNOW WHAT THE PROBLEM IS. THE FUEL FILTER HAS BEEN REPLACED. THE CAR ONLY HAS 40,000 MILES ON IT. THE "MACHINES" WILL NOT TELL THE PROBLEM SINCE THE COMPUTER DOES NOT INDICATE A PROBLEM.

Optional Information:
1994 Pontiac firebird 5.7 liter
