1993 Lexus LS400

RECENTLY THE CAR BEGAN TO STUMBLE UNDER ACCELERATION WHILE DRIVING UP A HILL OR MERGING INTO TRAFFIC OR MAINTAINING SPEED WHILE DRIVING ON THE INTERSTATE. I INITIALLY THOUGHT IT WAS A FUEL SUPPLY ISSUE SO I CHANGED OUT THE FUEL FILTER, WITHOUT ANY IMPROVEMENT IN THE PROBLEM. I WAS GOING TO CHANGE THE FUEL PUMP ALSO AND WHILE RESEARCHING ON THE INTERNET I LEARNED OF A PROBLEM WITH BAD ELECTROLYTIC CAPACITORS INSIDE THE CAR'S ECU (ENGINE COMPUTER) WHICH CAN MIMIC A FUEL SUPPLY PROBLEM. I AM A TRAINED ELECTRONICS TECHNICIAN, SO I REMOVED AND DISASSEMBLED THE VEHICLE'S ECU AND REPLACED 2 CAPACITORS (COST, LESS THAN $1) THAT I COULD SEE WERE BAD (LEAKING ELECTROLYTE FLUID). I TEST DROVE THE CAR AND THE "FUEL SUPPLY PROBLEM" WAS GONE, IT DROVE NORMALLY AGAIN AND DID NOT STUMBLE WHEN THE ACCELERATOR PEDAL WAS PRESSED. I ORDERED THE OTHER 5 OR 6 ELECTROLYTIC CAPACITORS IN THE ECU (FROM AN OUTSIDE SOURCE, THE DEALER WILL ONLY SELL A COMPLETE ECU FOR $2000 PLUS) TO HOPEFULLY PREVENT FUTURE OCCURRENCES. IN CONCLUSION, IT APPEARS THE BAD CAPACITORS ARE THE RESULT OF A "LARGE-SCALE INDUSTRIAL ESPIONAGE FOUL-UP". NOT A JOKE! THIS RESULTED IN DEFECTIVE CAPACITORS BEING USED IN MANY ELECTRONIC ASSEMBLIES (CONSUMER ELECTRONICS, AUTOMOTIVE, HOUSEHOLD, ETC.) UNTIL THE ISSUE WAS DISCOVERED, SEE WWW.BADCAPS.NET FOR THE STORY. I FORGET WHERE I LEARNED OF THE CAPACITOR PROBLEM ON THE LS400, BUT IT WAS JUST BY SEARCHING ONLINE. SO BASICALLY, LEXUS IS CHARGING CUSTOMERS OVER $2000 TO REPAIR A SAFETY ISSUE (THAT IS CAUSED BY LESS THAN $5 WORTH OF PARTS (RETAIL COST) AND A LITTLE SOLDERING SKILLS/LABOR) THAT WAS THE RESULT OF IMPROPERLY DESIGNED/MANUFACTURED ELECTRONIC COMPONENTS FROM THEIR SUPPLIER. *TR
