WHILE THE BRAKE IS HELD DOWN WITH THE LEFT FOOT AND A SLIGHT PRESSURE IS PUT ON THE GAS PEDAL THE CAR WILL SUDDENLY SURGE FORWARD. IT CAN MOVE ABOUT TWO FEET BEFORE I GET THE BRAKE ON HARD ENOUGH TO STOP THE CAR. IT FEELS AS IF THE VEHICLE WAS STRUCK HARD FROM BEHIND. THE DEALER HAS LOOKED AT IT TWICE AND SUGGESTED THAT THE BOG FOR "BREAK OVER GAS" LOGIC SYSTEM IS BEING FOOLED BY THE COMBINED PRESSURE ON THE BRAKE AND GAS AT THE SAME TIME, I.E., IF, WHILE BOTH PEDALS ARE PRESSED, IF THE BRAKE PRESSURE IS SLIGHTLY RELEASED WHILE THE GAS PEDAL IS STILL SLIGHTLY DEPRESSED THE COMPUTER THINKS THE IT HAS TO "CATCH-UP WITH THE GAS PEDAL AND IT SURGES FORWARD. IT HAS HAPPENED FIVE TIMES. IT HAS NEVER HAPPENED WITHOUT BOTH THE BRAKE AND GAS BEING SIMULTANEOUSLY APPLIED. IT BECOMES A SAFETY ISSUE WHEN IT HAPPENS AT A BUSY STOP SIGNED INTERSECTION WHILE WAITING TO MAKE A LEFT TURN ACROSS ONCOMING TRAFFIC, I.E., A PEDESTRIAN COULD BE STRUCK. I TRY TO AVOID THIS USING THIS TECHNIQUE BUT IT IS A HABIT THAT I'M SURE MANY DRIVERS HAVE. *TR

PULLED TO SIDE OF FRWY TURNED CAR OFF, SAT THERE IN DISBELIEF. I THEN TURNED THE VEHICLE BACK ON - ONLY CHECK ENGINE LIGHT STAYED ON. HAD POWER AS IF NOTHING HAD HAPPEN DIAG FOUND CODE P1738, P0847. GALPIN MAZDA CALLED TECH LINE AND THEY WERE TOLD TO PERFORM A REFLASH TO THE PCM. THIS HAPPEN AGAIN ABOUT 2 MONTHS LATER. BUT THIS TIME ALL WARNING LIGHTS TURNED OFF AFTER RESTARTING.
