how do you clean the EGR valve? ive heard people talkin bout doin this what does it help with or excatly what is a EGR valve?

 

There's plenty of posts you could read through describing the EGR valve and how to clean it, but alas...

EGR valve == Exhaust Gas Recirculation valve

Your's is located on the front of the engine, center of fan, pointing at you. It is about the size of a soda can and has an electrical connection on the top.

If you clean it, you'll need a new gasket for it.

To clean it, use some sensor safe carbon cleaner and an old tooth brush to clean out the passages. Simple as that.

 

What would he gain from cleaning it?

 

alright is there really a point in cleaning it? does to help it run better or what?

 

If you are having trouble with your idle (fluctuations) or have some missing/stumbling symptoms then yes. If it's running normally, it couldn't hurt, but probably won't give you anything but peace-of-mind.
