2002 Mazda Protege

THE CAR BEGAN TO SHUTTER AND DROPPED FROM 50 TO 25 IN SECONDS. THE CHECK ENGINE LIGHT (CIL) STARTING FLASHING AND THE CAR BEGAN TO STUTTER LIKE IT WAS GOING TO DIE, I PULLED TO THE SIDE OF THE ROAD AND THE CAR DIED. STARTED CAR AGAIN THE CIL CONTINUED TO FLASH, IT ONLY WOULD ACCELERATE TO 25 MILES AN HOURS EVEN WITH MY FOOT ALL THE WAY DOWN ON THE GAS. I TOOK IT TO THE A MECHANIC AND THE CODES WERE P0421, 171, 300. THE MECHANIC DID EVERYTHING FROM ENGINE FLUSH, SPARK PLUGS, OIL, AIR FILTERS AND INSTALLED A NEW CATALYTIC CONVERTER BUT THE PROBLEM PERSISTS. ITS NOW A YEAR LATER AND THE CAR IS DOING THE EXACT SAME THING. *TR

I HAVE A 2002 MAZDA PROTEGE. WERE THE UPPER PASSENGER SIDE MOTOR MOUNT ATTACHES TO THE CAR BODY, THE CAR BODY METAL IS SEVERELY RUSTED AND STARTING TO SEPARATE ON THE INSIDE OF THE ENGINE COMPARTMENT. I DID TAKE THE CAR TO A MAZDA BODY SHOP AND THEY QUOTED ME IN THE AREA OF $1,000.00 TO FIX THE ISSUE. I DO NOT FEEL IT IS MY RESPONSIBILITY TO PAY FOR THE FIX AS THIS IS AN AREA HIGH IN THE ENGINE COMPARTMENT NOT SUBJECT TO THE ELEMENTS. BASICALLY MAZDA HAS SOME PROBLEM WITH THE METAL, THE ANTI CORROSION TREATMENT OR THE FINISH TREATMENT TO THE METAL. THIS IS IN A PROTECTED AREA AND IF PROPERLY MADE SHOULD NEVER RUST. NEEDLESS TO SAY, A GOOD SOLID MOTOR MOUNT IS A CRITICAL ITEM. I FIRST NOTICED THIS PROBLEM ABOUT JUNE 1ST 2010. *TR

I HAVE BEEN WORKING ON THIS CAR FOR MAYBE 2 YEARS AND THE LAST FEW MONTHS IT HAS BEEN MISFIRING ON CYLINDER 3. IT SEEMS THAT MANY OTHER PEOPLE HAVE HAD THIS PROBLEM BUT CANT SEEM TO FIGURE IT OUT. I HAVE REPLACED EVERYTHING THAT HAD TO DO WITH ELECTRICAL AND NOW I THINK IT MIGHT BE SOMETHING TO DO WITH THE FUEL INJECTORS. ALSO THE SEAT BELT WOULD STAY LOCKED FOR ABOUT 10 MINUTES OR SO. *TR

CONSUMER STATES ENGINE MAKES A RATTLING NOISE WHEN STARTED. NOISE IS ALSO HEARD WHEN ACCELERATING AFTER VEHICLE HAS COME TO A COMPLETE STOP. VEHICLE HAS BEEN CHECKED BY DEALER WHO ADVISED A "VALVE" IN THE ENGINE IS CAUSING NOISE AND THAT MAZDA ENGINEERS ARE INVESTIGATING TO FIND A SOLUTION. CONSUMER IS VERY CONCERNED THAT ISSUE COULD COMPROMISE HER SAFETY WHEN DRIVING VEHICLE. TS
