i have a98 disco LE. i filled it up one day next thing i know the idle was running super high,,thought it was the gas maybe,,,,but several full tanks later still high and also running very rich. The idle does seem to drop down once it warms up. Con someone PLEASE tell where to adjust the idle i can't find the d*mn thing. PEACE

 

You don't want to try and adjust the idle down, you need to find out what is causing it to happen.
Do you have a check engine light?
Can you pull the idle down by pulling the throttle cable or hand rotating the throttle body?

No check engine light.... and no for the other two. Have any other suggestions??

 

Sounds like your idle stepper motor must be hung up, trouble is, I don't know where it is located on a 98 D1. You might ask around as to where it is and tray and clean it out with carb cleaner.
That's the only thing I can think of.
