Question about 1998 Land Rover Discovery
99 disco 1 engine surges 650 up to 1200 back down to 650 also when driving it doesnot want to down shift loses momentum then regainspower todrive at higer speed.
Sounds like idle control valve or throttle position sensor. It could also be the engine ecu is faulty but the other 2 issues should be looked at first as they are less expensive to address if you are going through a process of elimination. I would suggest taking it in to have it properly diagnosed by a competent mechanic. try rovercannibal.com for parts when/if you need.
