runner Posted November 15, 2005 Share Posted November 15, 2005 Hope some one can help me. My 99 RX300 radio is driving me crazy. When I tune to AM alot of the time there is a buzz coming thru the speakers in rythm with the acceleration of the engine. Not sure if this is a grounding problem or what. I've replaced the antenna twice already since it got bent both times, but haven't touched the connection behind the rear panel. Quote Link to comment Share on other sites More sharing options...
COZ Posted November 15, 2005 Share Posted November 15, 2005 Have you recently changed you spark plugs? If so you may have damaged a spark plug wire or bought non-resistor type spark plugs. Quote Link to comment Share on other sites More sharing options...
