CAR DIES AT AROUND 30 -40 MPH
 

I RECENTLY BOUGHT A 1987 CAPRICE CLASSIC WITH THE 305/350 PACKAGE.THE GUY I GOT THE CAR FROM SAID IT RUNS JUST A LONG AS YOU DON'T GET ON THE GAS LIKE I LIKE TO,AND AFTER THAT WE NOTICED FUEL LEAKING FROM THE ENGINE BAY.LONG STORY SHORT I'VE REPLACED THE FUEL PUMP AND FILTER,IGNITION COIL, SPARK PLUGS AND WIRES.THE CAR STILL DOES THE SAME THING.IT WILL BURN RUBBER AND RUN ALL DAY BUT WHEN YOUR OUT ON THE HIGHWAY IT WILL JUST CUT OFF, BUT ALWAYS CRANKS BACK UP.I EVEN HAD A BUDDY OF MINE TO PUT HIS MATCO OBD-1 SCAN TOOL ON IT AND IT SAID NO CODES WERE FOUND AND NOTHING REALLY BESIDES THE MIXTURE IS RIGHT.SO DOES THIS SOUND LIKE THE CARB TO YOU GUYS? THATZ WHATI WASTHINKING AND I HAVE A GREAT DEAL ON AN EDELBROCK INTAKE AND CARB.CURRENTLY RUNNING THE QUADRAJET
