apezam Posted May 13, 2005 Share Posted May 13, 2005 I'm a new owner of ls 96 with 130K. The car produces buzz sounds for 2-3 min. after the engine is turned off. I just notised it today. It seems coming out from the engine, but I am not certain. The sound is rather quite. It comes in equal intervals. It is like there is a cell phone buzzing or vibrating hidden under the hood. I appreciate any theories and possible explanations. Many thanks, R. Quote Link to comment Share on other sites More sharing options...
ED. Posted May 14, 2005 Share Posted May 14, 2005 I am not too familiar with the Lexus IHKA system but I might guess it to be the stepper motrs which sontrol the air flaps. If it isnt that my second guess woudl be something under the hood that is syncronizing? Thanks ED Quote Link to comment Share on other sites More sharing options...
mehullica Posted May 14, 2005 Share Posted May 14, 2005 Normal noise from the charcoal canister. Updated part was made to reduce the noise. Quote Link to comment Share on other sites More sharing options...
