I've just gotten a 2000 Jaguar xk8 convertible. It looks great but has some issues. Restricted Performance light comes on and it feels like it's running on 6 cylinders. The light comes and goes so I've been doing some homework to solve this issue. As it turns out, many things can create this problem. I charged up the battery as recommended on youtube and it seems to bring new life to the engine for about 20 kms. I was having a "happy pants" time when the dreaded restricted performance issue reared it's ugly head and made me sad. Could it still be a battery issue? I can hope but between coil packs, spark plugs, throttle body issues or all of the above I may be chewing my cheek for a while yet.
Please feel free to chime in folks.

 

Welcome to the forums woodcarver,

(I've moved your post from the end of my *New members - a MUST read if you have just signed up* thread to a new Intro of your own.)

Almost certainly you need a new battery. This alone may resolve the restricted performance issue but the odds are against it. The only way to determine the cause is to have the DTC's (Diagnostic Trouble Codes) read. If you post the codes in XK8/XKR forum, members will decode and advise on required actions.

Follow this link https://www.jaguarforums.com/forum/xk8-xkr-x100-17/ to the XK8/XKR forum for help, advice and information. The 'HOW TO' thread at the top is a good place to start for information on regular issues.
