2007 X-Type Stumble

2007 X-Type stumble at low speed, Jaguar club member suggested fuel injector cleaner that worked for awhile, switched to Mobil gas that cured it for good. Has been a reliable car since 2008 when purchased on Ebay, now has 149000 miles.
Hope this helps someone with this problem.

That’s right, I put fuel injector cleaner into the tank every spring
and do not have any fuel problem
