Dgoude Posted June 6, 2010 Share Posted June 6, 2010 Hello everyone. I have a '99 ES300 with 165k miles on it. Still runs great but as the years go by I'm getting slower and slower. I have replaced the spark plugs and the Mass Air Flow Sensor. I change the oil every 3k miles with high mileage oil and filter. But I'm wondering what other things I can do to tune her up and make her respond a little better. I know I'll never have the engine of a new car again, but anything you can offer that would help her purr a little better would be appreciated. I have noticed that it gets worse in warmer weather if that helps you offer any other advice. Thanks everyone! Quote Link to comment Share on other sites More sharing options...

igbeserk Posted June 7, 2010 Share Posted June 7, 2010 yep clean the throttle body and make sure it opens all the way. that can cause performance issues. Quote Link to comment Share on other sites More sharing options...
