toyomoho was letting us know the electronic pedal design is fitted to a 2008 model camry model

its not an old school cable

I am suggesting the pedal fitted to the 2008 might be the the cause and cant be dismissed

check which pedal type is fitted to your vehicle

if it is a denso type the revs hanging on the problem might be else where

if not a denso type......you need to have the pedal checked out first ....then look elsewhere
