AFTER THE FIRST MONTH I OWNED THE CAR (BOUGHT AS A PREOWNED VEHICLE) THE CHECK ENGINE LIGHT CAME ON DURING THE GUAGE FAILURES I HAD THE CODE CHECKED AND IT WAS DETERMINED THE SPEED SENSOR WAS BAD. I BOUGHT AND REPLACED THE SPEED SENSOR WITH AN OEM PART. HOWEVER THE GUAGE FAILURE WAS NOT FIXED IT STILL HAPPENS. THE INCIDENT DATE STARTED 21FEB2003 AND STILL PERSISTS AND THE NUMBERS OF FAILURES I...
