are you guys aware of the need to replace your ECU capacitors?

In regards to it drying out from under-use, that could be the case for me as my car only has 120k miles (as far as I know) which is not a lot for a 1993 car. So, at one point or another, it could have sat dormant for a while. In fact, I bought it from a used car lot and the ECU died that day!

OK, I just received my rebuild ECU back from Lexus and WOW!
I was getting 4 CEL readings before but they are all gone now and surprisingly the most aggravating ones, the knock sensors and a/f.
my car wasn't starting in cold weather and i plugged my ecu back up and it started immediately without a crank!!!

O.L.T is correct, I simplified the details to a basic level. In my defense I to will post a link http://en.wikipedia.org/wiki/Capacitor_plague
and I believe that the failure is due to heat. but that is my opinion.
The repair I had done was $60 link http://store.driftmotion.com/static/...capservice.php

Quick way you can do a visual check up if you can get the ecu out and open it, you can see the bad one's, but the ones that are just starting you have to look really close at the bottom of the cap, it will look like dust is collected on oil/water Liquid etc... and the pro's can test each cap for uf and volt's.

Hey guys, I have a 92 SC400 that I'm Renovating(everything) and my car was having some problems which was diagnose by a Lexus certified master tech, and the cause was the 1UZ ecu. So I took it out and opened the ecu, to my finding there was 1 capacitor that had corrosion all around it, and another two that started leaking. Since driftmotion was close to where I live, I met with Aaron, and as soon as he looked at the caps and the brand, he told me that this was one of the bad caps Toyota used. drifmotion has repaired alot of **1JZ** ECU's, according to Aaron @ driftmotion.com the 1UZ ECU had more Capacitors then 1JZ. It's getting fixed (replacing all caps)now, I will post pictures of the bad ecu caps, and will let you know about the before and after results. I thought about doing it myself, but did not want to risk damaging the ecu(static electric shocks will damage alot of components in there)
