1993 LEXUS LS400 Fuelpropulsion System Problems

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...
