The restricted performance is the limp mode operating
the next step is to have the fault codes read to find the area of the fault ( engine or transmission or both) and have the fault rectified before more serious damage is done

I have a 99 jaguar xj8 van den plaus edition. It says resdtricted performance when it Gets warm and check eng. Light stays on. I replaced the computer any ideas

For the money you spent on another computer, you could have brought your car to a qualified mechanic and had the problem correctly diagnosed and repaired. 'Restricted performance' meant the computer saw something wrong in the engine, and restricted the performance to keep from destroying the engine. You killed the messenger and still have the same problem.
