Related Ref Number(s): SECTION XT303, NO. 13, XT303-13
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.
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.
