Jaguar Repair Problems? Ask a Jaguar Repairs Expert.
Hello and thanks for using justanswer.com
It could be a number of faults like an electrical malfunction such as the transmission control module or electronic throttle. If you had the problem after some wet weather or after a car wash then water may be leaking into the TCM. To be sure we will need to have the vehicle scanned for the stored fault codes. A Jag factory tool is needed to do this but we can try again using a generic OBD II scan tool to see if we can read the codes. In the mean time we should also check the battery and cable connections to make sure all are clean and secure as well as the throttle body connector. I do not recommend we disconnect anythign until we get the vehicle scanned. Let me know.
