After taking my jag to the tech the upstream and downstream sensors were replaced. The timing chain kit was purchased and this too replaced.
But this lady just keeps jerking on steady acceleration hard acceleration is even worse. I have spoken to a mate of mine who thinks FUEL MAPPING could solve this problem.

Any Advise Anyone

 

Welcome to the forum Jon,

There's three different models of XJR produced between 1995 and 2009 but, as you mention timing chains, I'll assume it's the X308 of 1997 to 2003.

If so, follow this link XJ ( X308 ) XJ8 / XJR - Jaguar Forums - Jaguar Enthusiasts Forum to the X308 section for help, advice and information.

Remember to add vehicle details to your Signature to help others to give relevant advice. Go to the User ID button on the left of the top menu bar, then Settings & Options under Your Control Panel. Select Edit Signature and enter the details.

You can also visit the 'Other Areas' Region section by following this link https://www.jaguarforums.com/forum/other-areas-43/ to find other members in SA.

Enjoy the 12 Jaguars and the forum.
