Hi,I have a 1999 xj8 3.2 litre saloon with 74,000 ks on the clock.It shows the restricted performance and orange light every now and then mainly at low speed like in town and slowing down at the traffic lights.I have put new coils in and also new spark plugs.The plugwells had oil in some of them.The rocker cover gaskets were resealed but new ones are on the way.It has not fixed the problem.I took the car down a back road and gave it a blast up to 200ks for a couple of miles to (tune it up).Worked well for the next 1200ks or so but is back to its old nonsence again.It is driving me crazy and costing me heaps.I love the car but my wife is on my back about it all the time.Shorly someone else has had this problem and found the answer.My beautiful Jag cant be the only one in the world to have done this. HELP ME PLEASE. GRAMICK.

Hello, Gramick,
Welcome to the forums from ElinorB.

I have had "Restricted Performance" come up and the yellow engine warning light come on. Mechanic put the computer on it and gave the priceless advice.... get on the motorway and give it the bollocks! After an exceptionally hard and fast run (locked in 4th keeping the revs above 4000) which at first was subject to some engine cut outs, the soot in the catalytic converter, caused by many short town runs seems to have been burnt off and the restricted performance signals have gone........
