Hi, this is Suzette regarding the 1998 land rover discovery. I have driven more than 30 miles, and the idle has still not lowered, I have changed the idle sensor, and the computer but its still idling high. What else can I try.

hi i am shannon i will help on this issue

sgm11155 :

the bigest thing to cause a high idle is an engine vacuum leak.

an exspearance tech can hear the leak and then pin point it with carb spray or propain gas.

one thing you can have done is have the computer scanned for what step the idle motor is on. on a discovery if the data shows 180 or the motor is all the way closed and the idle is to high. you do have a vacuum leak.
