Daughter's 07 Camry with the 2AZ-FE engine has been plagued with low idle since her battery had to changed. I've read on Toyota forums that the ECU resets and default to when the vehicle was new. Some people have found relief by cleaning the throttle body. Others have left the battery unhooked for a half-hour. Some have said it relearns the vehicle's current parameters after a certain number of miles. This has been going on for more than a week. Her friend unhooked the battery for a while and hooked it back. It improved for a short period of time and then returned to the low idle. He also said the alternator tested good. I still have my doubts about the alternator. I may take it off and have it tested outside the vehicle. Any other suggestions would be appreciated. Car has 120k miles.
Thanks,
