I have 2002 toyota v6 camry 3.0L, i went and got a new battery, after installing the new battery all the gauages in the dash went jumping every where and so i guess that was a reset. my question is, is their a such thing on the new toyotas when replacing the battery without a memory savor it resets the ecu and u have to clean out the throttle body in order for it to run normal again cause of the mileages and the carbon buildup.
