Having problems with your 1994 Land Rover Discovery ?
When I first start my 94 disco it idles fine but when it warms up the idle goes high then low high then low. Its up and down. What could be the cause? I changed the plugs and wires and cap but it still does it. The smog ref won't pass it because it does that.
It sounds like a idle air sensor they can be very expensive and if you are taking one off yourself you will need a torx specialty tool with a security indentation.
