at some point in time the purge hose on my 4.0 got intentionally plugged. not sure what the impact is and where to connect it to if it is necessary. a photo of a 1998 4.0 showing the purge hose would be very helpful. if u need more info, pm me at fabbrojo@xplornet.com....thnx

 

I you tell me what the purge hose is, I will be happy to look at mine and tell you where it connects to.

 

i am going to try and attach a picture of the purge hose.....

 

Looks like a coolant hose that goes from the top of the intake manifold to a connector on the bottom side of the throttle body. Probably there to prevent the throttle from freezing up in extreme cold. Hope that helps.

 

the vacuum is towards the visible side of the purge hose on the diagram. but i will check to see if there is a connector on the underside of the throttle body. if i pull the plug from the purge hose, the idle jumps to apprx. 2000rpm. nothing to connect to under the throttle body. if u can offer a picture of where it connects, perhaps i can figure it out. thnx,,

 

anyone with a 98 range rover 4.0 out there ? please take a look at your engine and see if u have this hose. in need of help !!!!
