Jaguar Repair Problems? Ask a Jaguar Repairs Expert.
Hi, I'm Chad ,Welcome To JustAnswer, I'm reviewing your question and I will be be posting a replay ASAP
1-is there a check engine light on?
2-if you scanned & retrieved any faults codes ? if you did let me have the code numbers if you have them?
The most common cause will be the TB ( throttle body itself) or it is a vacuum leak causing it )
3-does it reset itself each time you cycle the ignition switch ?
4- what is the mileage on it ?
Please let me know
