Hi, I have a 2003 Jaguar X-Type and when cold or driving slowly with little power eg when putting in garage there is a popping noise like a back fire coming from air intake?

This happens when vehicle engine idles slower that normal idle speed eg when driving into garage without enough power on accelerator or when stopping eg from normal speed to idling.
Do you
have the same problem?
Yes
No

ARTICLE BEGINNING
Issue
Some 2002 MY-ON X-TYPE vehicles may exhibit driveability/hesitation concerns. Customers may also complain about a hissing noise from under the hood.
The concern may be caused by a vacuum leak from the O-ring seal on the Intake Manifold Tuning (IMT) valve.
The O-ring is now available separately to avoid the need to replace the entire valve.
Action
In case of a customer complaint of the above condition check whether the Intake Manifold Tuning (IMT) valve O-ring seal has failed. If so, DO NOT replace the IMT valve since the O-ring seal is now a serviceable item. Follow the workshop procedure outlined below.
Workshop Procedure
Installing a new upper IMT valve O-ring seal.
