tomb57 Posted January 4, 2012 Share Posted January 4, 2012 I have a 2000 RX300 that has sometimes a low idle/vibration. It sounds like the noise an engine makes when you !Removed! the timimg. We had the timing belt replaced about 12,000 miles ago at about 105,000 miles, that also took care of a louder than normal "belt noise". Now the noise is back also. Can the noises by related, and do timing belts need readjusting? Mileage is down a littls (1-2 mpg) but then it is winter here in Wisconsin. Gut feeling, it's not like it used to be. Any help would be greatly appreciated. Quote Link to comment Share on other sites More sharing options...
