Question about 2002 Lexus RX 300
It was soft at first but got louder. Our local mechanic replaced a piece of the exhaust system and it seemed to get less noticeable but now it is getting louder again. It's like a piece of metal is loose or something. Any clues?
IF this is occurring on light acceleration or when the motor is under load then it may be detonation in the combustion chambers . IT is from air/fuel ratio incorrect and ignition timing incorrect. Run the fault codes to check for codes associated with the air flow and the exhaust as the ECM is having difficulty adjusting the settings for the engine.
