Crazy High Idle - Thursday night - please help
#11
Michigan? Still probably pretty cold there. Engine can't run fast without a lot of air and fuel. There are two cables that connect to the throttle body on the very front/top of the engine right in front - that's the throttle body. You can pull on the exposed part of cable and see it pull the throttle bellcrank open. When you release it they should go all the back to a physical mechanical stop. Make sure it does, if it does not, that the problem. Also, with it in the closed position, there shoudl be a tiny bit of slack in the cables.
I doubt it is the throttle, my guess is it is a stuck idle air valve. - google images for LR Discovery idle air valve. Disconnect the hose from the valve to the large metal piece (upper intake). Put something large and metal that fits tightly in the hose and is impossible to fit through the hose in to the end. Start engine. My guess is it will not idle due to no idle air. If that is it, try putting the idle air valve inside at a reasonable temperature, probably just stuck due to cold temps.
Good luck.

I'll try to tackle it again tomorrow night and pay more attention to the dash while starting her up. I don't think the oil light came on but then again, I didn't even look to see what the RPMs were actually at as I was too freaked out with the spectacle Bertha was bestowing upon me. She was NOT happy and I did end up having a good cry tonight. This vehicle gets me every single time. I think the new dent in the hood pushed me over the edge - self inflicted by my stupid ice scraper last month. Thanks for the input everyone. I'll post back when I know a little more.

So typically I have epiphanies at 4:00 in the morning. Today it came to me at 6:00. I just realized that when I was jump starting Bertha she sounded as if she'd turn over normally once she had enough juice. I probably should have just put a slow charger on her and waited but I was impatient and wanted to get her going again. Hopefully I didn't do any harm to the alternator, etc. Anyway, it just occurred to me that I put the pedal to the metal when I heard her trying to turn over, she caught, I was relieved, and that's when all hell broke loose. Something is stuck. I'll go ahead and clean everything tonight and see if I have any luck. Thanks for all of the input. I appreciate it
