restricted performance light comes on every 2 to 3 days car resets it self after about 1 hour just started hapening otherwise auto runs great
I would see if there are any trouble codes pending.
I have the same thing happening. Have you found an answer.
I bought a 2000 XJ8 just about two weeks ago with no manual. Today for the first time the restricted performance light came on but went off after about fifteen minutes. Did you get an answer to your question?
