First I recommend we check the battery and cable connections as low voltage can be the cause. If all is clean and secure then we will need to have the vehicle scanned for the stored fault codes. A vacuum leak can also be the cause. A Jag factory tool will be needed but we can try a generic OBD II scan tool to see if there are any stored faults. In the mean time also check the air intake tubes and hoses. Let me know. Also provide the year and model. Thanks.
