Jaguar Repair Problems? Ask a Jaguar Repairs Expert.
There are a few different possibilities which can cause this. It can be a number of engine sensors or actuators causing this like the mass air flow sensor, knock sensors or possibly an ignition coil. Some of these May fail and not cause an performance problems. It may not be that serious right now but may lead to something else. To be sure we will need to have the vehicle scanned for the stored fault codes. A Jag factory tool will be needed to do this but we can try using a generic OBD II scan tool available from your local parts store. If you can get me the fault code number it will help me better determine the possible causes.
