I am currently working on a friends '91 YJ that he sank in the river last weekend. I have changed all of the fluids including the fuel, replaced spark plugs, wires, filters, inspected distributer inside and out. The symptoms are running rough and won't idle when warm. The check engine light gives me the diagnostic code 24 which is "Throttle position circuit out of range".
Does this code mean anything to anyone, or has anyone troubleshot this type problem before? I really don't even know what a throttle position circuit is so any help at all would be appreciated.
