1991 Lexus LS400

THIS LEXUS LS400 CAUGHT ON FIRE DURING SMOG CHECK AND BOTH NEW CATALYTIC CONVERTERS WERE ON FIRE AND 2 FIRE EXTINGUISHERS WERE USED. THE CAR IS STILL DRIVE-ABLE AND ONLY TAKE VERY SHORT SHORT "STOP AND GO" TRIPS IF YOU REALLY WANT IT GO FROM POINT A TO B. I HAVE ATTACHED 2 PICS ON THE SMOG CHECK PLACE AND A REPORT FROM THE SMOG CHECK PLACE BEFORE IT CAN FINISHED THE SMOG TEST PROCESS. I ALSO HAVE A FRIEND GOT A LEXUS ES300 1998 SIMILAR PROBLEMS WHICH HE SPENT AND REPLACED FUEL INJECTORS, TUNE UP, MAF, OXYGEN SENOR ETC BUT GET NO WHERE.. IT IS DEFINITELY AN INTERESTING ACADEMIC CASE AND ALSO A UNSAFE VEHICLE IN THE PUBLIC; WELL, I DO NOTICE EVERYONE GETS THEIR ATTENTION STARTS LOOKING AND SMELLING. ADDITIONAL INFORMATION -- THE 2 CATALYTIC CONVERTERS BECAME RED-HOT AFTER CHANGING AN ALTERNATOR FROM O'RIELLY AND IT WAS SUSPECTED TOO MUCH "UN-BURNED" GAS FROM ENGINE COMPARTMENT AND BURNT AT THE CATALYTIC CONVERTERS; A LOT OF EMISSION CONTROL PARTS CHANGED SUCH AS 2 CATALYTIC CONVERTERS, MAF, TUNE UP, MUFFLER CHECKED, PRESSURE PUMP CHECKED AND AMONG OTHER THINGS BUT NO RESULT.
