Went to the Jaguar dealership, they seemed confused and had a list of what was the problem might be for my XJ8. Decided to stop by Smyth Auto. Drove in explained the issue, he pulled a car from the repair bay, showed me the issue had the mechanic fix it on the spot. I was shocked and surprised inside of a half hour out on the road. PROBLEM SOLVED and will never go any place else. A true honest and beyond qualified.
