I had the same problem and found that the PCV breather hose was leaking, creating a vacuum leak. The codes for the error have translated to "bank 1 too lean, and bank 2 too lean." Check your PCV breather hose (it is located just above the intake air filter box) and see if that looks like it is leaking (you might hear air escaping too). You will also have to reset the computer afterwards to get rid of the error. The computer can be reset like the first solution explained, or take it to an auto parts store and have them use the code reader device to reset it.
Hi
First line of attack, is to reset the on board computer, which are notorious for giving problems, especially if you have run down the charge on your battery.
Disconnect both battery terminals, switch on the ignition to start 5-6 times, to erase the computers memory, and then reconnect the battery, with the positive terminal first.
Then give her an extended road test, to see if a problem returns.
Good Luck !
If you think I have been of help, give me a FixYa rating please.

when I first start the car engine seems to run normal. After about a minute or so, engine fault and cruise not available light flashes. Rpm's will not go above 2500 and max speed is 15 to 20 mph. the model is a 2002 Jaguar X-type.
cruise not available engine management on. Car wont accellerate. Car was running fine down the motorway when it just came on.
Do you mean that your Jag loses performance when the check engine light is on?
