Just joined this site so hello to everyone.
I was hoping that someone may be able to shead some light on the problem that I have.
I own a KK model jeep with a 3.7lt and the fuel economy is very bad, I have spoken to Jeep here in OZ but it has been to no avail.
After a considerable amount of work done by myself I have tracked the problem to the EGR valve, it appears to be opening when it shouldn't and it does not close when it is suppose to either. When I pull up to a set of traffic lights it is still open and causes the engine to idle rough and in some cases stalls.
If anyone knows how to rectify this problem or bypass the valve completely that would be great.
Sorry for the long msg for my first intro.
