Re: bad caps of the 1990's played havoc with car ECU's
Hi. I have a 1993 Camry. It has done over 300 000kms. In the last year it has developed a bad idle on start up but improves when warm. Engine is very good, excellent compressions, excellent sparks. I have spent many hours probing all the sensors and have found no problems. I have also replaced coolant sensor, oxygen sensor, MAP sensor, ignition coil.
Checked plugs, checked leads, cleaned idle control motor, checked throttle position switch, cleaned EGR valve, cleaned all terminals.
As a last straw I was about to fork out the money for ECU.
Anyway, I found this site and so decided to pull out the ECU out to check the Capacitors, and what do you know... it looks just like the photo above. Leaking caps galore. I will post pictures soon after I have a go at the repair.
