INTERMITTENT PROBLEM-WHEN CORNERING ENGINE LOSSES POWER, SPUTTERS/SPITS, BACKFIRES THEN CATCHES AND STARTS RUNNING AGAIN AND THEN YOU HAVE A VERY RICH SMELL LIKE ALOT OF UNBURNT GAS. GAS TANK IS FULL SO ITS NOT SLOSHING GAS AROUND AND MISSING THE PICKUP IN THE TANK. I TOOK IT TO CHEVY AND THEIR BEST TECH CANNOT FIND ANYTHING AND IN FACT 3 DIFFERENT PEOPLE DROVE IT WITHOUT A SINGLE PROBLEM. I DROVE IT HOME TONITE (ABOUT 17 MILES)AND WAS OK BUT AM AFRAID IT MAY START ACTING UP AND LEAVE ME STRANDED. ABOUT 8 MONTHS AGO THE FUEL PUMP WENT OUT AND CHEVY INSTALLED THE NEWER STYLE PUMP. ANY IDEAS?
THANKS
