elzorro500 Posted September 22, 2009 Share Posted September 22, 2009 Hi there! First post and already a question. I just bought a '99 ES300 and I can't help but to notice that it idles at 1250-1500RPM even when it's warmed up all this with Air conditioner off. When I turn the A/C on, the RPM's drop to 900. Any thoughts on what might be causing this? Computer scanner is not showing any malfunctions. Thanks, -William Quote Link to comment Share on other sites More sharing options...
