2002 xType, I had Autozone to test and there were no stored codes
Jaguar Mechanic: Richard, Jaguar Technician replied 2 years ago

OK usually when the engine light is on there should be fault codes and when it blinks it is a severe misfire. I would start by checking for vacuum.leaks. I see issues with the intake seals and gaskets causing the engine to run lean and miss. Let me know.
