ecu. help. what and where to buy transistors
T 786 is the number next to transistor on ecu circuit board. I need to know where u buy these at or have to order them. Its off a 95 ls400 completely burned and broke apart won't allow me to upload pics. Its a tiny black box with 3 of the spots to solder on one side and only one on the other.hoping this is the reason for running like crap. Thanks in advance

The T number is what number it is on the board, it would not be the identification of the item. You have to look for id numbers on the piece itself. And likely the same place you get the capacitors from would also have that.
A bad capacitor likely ruined it.
If you had the information on the circuit boards you could readily id it. That is my big gripe about all the little black boxes in all cars etc now days.

If you have the transistor specs contacting a local electronics parts supplier or calling up/looking through Digikey's site would be my suggestion. http://www.digikey.com/
Radio Shack has a new owner, hard to say what that store will be. The electronic parts was becoming less and less of their stock. You can give them a call and you'll probably have to explain what a transistor is to the sales person.

Went to radio shack no help and same with a big name electronic place here called Eliot electric. Any ways they told me there is nothing the can do for me capacitors yes because of having I'd numbers on them but transistor or transformer what ever it may be is in findable. Apparently Lexus doesn't provide a schematic for helping with that. I ended up purchasing a refurbished ecu and that still didn't fix my problem of running rich.actually my car wouldnt even start. It would turn over but no start.For some stupid reason I never thought to check fuses under hood. I found dome light fuse and efi fuse was out new about dome but not efi. Anyways replaced it car still wouldn't start.decided to call it a night get car drivable again and put old ecu with burnt parts and caps that look to be going bad. But it ran great from then on. I have no idea what those two burnt pieces do but every things works perfect again. Weird ****. Thanks for help though guys!

Incidentally did you read the failure codes?
