2007 Toyota Avalon XLS
 This is my 3rd Avalon -1995, 2000, 2007. I didn't feel comfortable with the drive by wire acceleration. Two trips to the dealer where they scanned the computer didn't show anything. Finally, on Edmunds forum someone had TSB EG 029-07 regarding the tranny controller. Brought to the dealer with this info. The reprogrammed the controller and this fixed the problem.
