Do ECU's ever go bad gradually? 200 1992

posted by  someone claiming to be Dharvey on  Sun Apr 13 10:53 CST 2003 [RELATED]

Last fall I reported on a mystery engine hesitation combined with engine code 232 ("compensating for lean mixture at cruise"). Eventually it turned out to be the ECU. I replaced it with a used 561 that seemed to solve the problem. For a while.

Recently my gas mileage has started getting a little worse, and the exhaust note is starting to sound like a Chevy Cavalier. The engine sounded this way before I changed the computer--afterwards, it had a huskier, deeper tone. I checked a few days ago, and Mr. OBD wasn't showing any engine or ignition codes.

Is my foot just getting heavier, or is the current ECU starting to croak on me?

Thanks for any help you can provide.

Doug Harvey
