20050911FUEL SYSTEM, GASOLINE:FUEL INJECTION SYSTEM
WHEN DRIVING UP HILL OR IF YOU GIVE IT MORE GAS TO PASS SOMEBODY THE ENGINE HESITATES SEVERELY AND THEN STALLS ON YOU IN THE MIDDLE OF THE ROAD. AND THEN YOU HAVE TO TURN OFF THE VEHICLE FOR ABOUT TWO MINUTES BEFORE IT WILL EVEN CRANK UP AGAIN. THIS HAPPENED TO ME FOUR TIMES WITHIN TWENTY MINUTES OF DRIVING. IF IT WOULD HAVE BEEN SOMEONE WHO DON'T KNOW WHAT TO DO IN THAT KIND OF SITUATION THEY COULD EASILY RUN OFF THE ROAD OR HAVE SOMEONE WRECK INTO THEM, ESPECIALLY WHERE I LIVE IN THE MOUNTAINS GOING AROUND A CURVE IF IT WAS TO QUIT ON YOU AND THE POWER STEERING GOES OUT AND ENGINE SHUTS DOWN YOU COULD EASILY RUN OFF A CLIFF. I CONTACTING MY ONSTAR AND HAD THEM DO A DIAGNOSTICS ON THE VEHICLE AND THEY SAID THAT THE POWERTRAIN CONTROL MODULE WAS AFFECTING THE ENGINE FUEL SYSTEM WHICH WAS CAUSING THE VEHICLE TO ACT THAT WAY AND THAT IT NEEDED TO BE FIXED RIGHT AWAY. HOPEFULLY IT DON'T HAPPEN TO SOMEONE ELSE AND THEY HURT BECAUSE OF THIS DEFECT. I DRIVE A 2004 CHEVY TAHOE WITH ONLY ARO
