denn77 Posted June 8, 2005 Share Posted June 8, 2005 I want to try cleaning my egr valve to solve a sluggish acceleration problem on my 99 es300. First off, can somebody tell me where this thing is? I found something directly underneath the throttle body that resembles the egr valve but I'm not sure. Also, is there a way I can test if the egr valve is the problem or not? thanks, Denn77 Quote Link to comment Share on other sites More sharing options...
VGR Posted June 8, 2005 Share Posted June 8, 2005 By 1999 I think the ES300 V6 had Variable Valve Timing with Intelligence. If so, your engine does not even have an EGR valve. Have you tried cleaning the throttle plate yet? Quote Link to comment Share on other sites More sharing options...
denn77 Posted June 8, 2005 Author Share Posted June 8, 2005 Yes, my es300 does have the vvti engine. Are you certain it doesn't have an EGR valve? I thought it did but you may be right since I couldn't really find it. How can I clean the throttle plate? Is that inside the throttle body and do you think that would cause the car to be sluggish intermintently? I have noticed that my car is peppy usually 10 min after startup and becomes intermittently sluggish after it is fully warmed up. Also fuel mileage is not that great. Your help is much appreciated.

mehullica Posted June 8, 2005 Share Posted June 8, 2005 Remove and clean the MAF sensor with a good electronic parts cleaner Quote Link to comment Share on other sites More sharing options...
denn77 Posted June 8, 2005 Author Share Posted June 8, 2005 I've actually already removed and cleaned the MAF sensor. It did help with rough acceleration problems which are gone now. The only thing left is this sluggish acceleration problem and it's intermittent. It almost feels like the timing is off. Quote Link to comment Share on other sites More sharing options...
melhadri Posted June 8, 2005 Share Posted June 8, 2005 Get a motorvac service. Call motorvac and ask for local distributors of the motorvac carbon machine in your area. The distributors should be able to provide you with a list of local shops that have purchased the machine from them. I am going to soon have a motorvac done to my car. Its supposed to work wonders. The 800 number can be found at www.motorvac.com. Quote Link to comment Share on other sites More sharing options...
