On my 1999 XK8 Jaguar "performance compromised" comes up on my digital read out and then the "Check engine" light comes on. Performance compromised goes out but the check engine light stays on. Ran a diagnostic on it and it comes up clear and the check engine goes out when reset. It does show lean fuel on the diagnostic. What do I need to do?
