Jaguar Repair Problems? Ask a Jaguar Repairs Expert.
Hello and thanks for using justanswer.com
Did you have a chance to scan the vehicle for the stored faults? Does the vehicle go into a full limp mode?
Ok thanks for the additional info. This does sound like a failure with the throttle but it can also be the electrical connector pins that are causing the issue. We will need to first scan the vehicle to see what the stored fault codes are. A Jag factory tool is needed to do this but we can try a generic OBD II tool available at your local parts store to see if we can read any faults. Let me know.
