halikias Posted August 11, 2005 Share Posted August 11, 2005 i have a 2000 rx300 fwd with 74,500 miles. the check engine light just came on. i also noticed when my key made contact with the ignition, a strange buzzing sound came from the lower part of the engine. the sound is faint and could have been there a while - i just noticed it today when i was under the hood. are these symptoms related?
