OMEGALS400 Posted July 12, 2003 Share Posted July 12, 2003 When turning the Air conditioning On or Off the rpm drops for a few seconds then picks back up and you for once hear the engine working for a brief moment. I suppose that this is a normal occurance of a '93 LS400, i'm not sure if this happens with the newer models. anyhow, i am wondering if there is any way to suppress this. Everything about this car is smooth, no noise opperation, except when you turn the A/C on or off. Is there a solution? Thanks. Sahak Quote Link to comment Share on other sites More sharing options...
jzz30 Posted July 12, 2003 Share Posted July 12, 2003 the only solution to that is to not turn on your a/c when you run your a/c it adds a significant amount of drag so the rpm rises when its on and slows down when it disengauges Quote Link to comment Share on other sites More sharing options...
