My parents have a 97 300ES. It started running roughly and the Lexus dealer told thyem it needs a new computer -- only $2000. I talked to the service manager and was told the ECU has leaky capacitors. I see plenty of shops that advertise online to do it -- and plenty of poor reviews and tales of woe from dissatisfied customers. I will appreciate advice from forum members about a good place to send the ECU for repair. Thanks!
