I agree, pull electrical plug from the valve. If idle stays High, you have broken wires or a stuck valve. I recently gave Euro500 a length of wire with a cap for the same harness - this case it was the temp sensor. If you are board, rebuilding that harness for temp, idle 6Ē up with heavier gauge wire a d hear rated shrink is a good mod.
