You were lucky the leakage didn't get in between the PCB layers. Once that happens, it's game over for the ECU.I have a 26 year old Lexus LS400. About 8 years ago it started running poorly. I checked everything I could think of and the codes I got varied from one thing to another. I decided to check the ECU (computer). I removed it from under the dash (glove box area), opened it up an saw where there was a tobacco like juice running out of one of the capacitors onto the circuit board. There were six capacitors on the board. I View attachment 133238 ordered all six from DigiKey, cleaned up the board and replaced the capacitors. Problem solved for $7.00.
