I have 03 jaguar s-type with engine symbol and dash reads restricted performance

You need to go and have any fault codes diagnosed. The jag dealership is probably the best option.

The symptoms you describe could be attributed to a faulty oxygen sensor or blocked catalytic converter

First thing to do is get the battery checked and replaced if necessary. If the problem continues, it will be necessary to have a pro-shop check the fault codes (go to a Jag specialst, not a dealer)

This sounds like your fuel pump is failing or has a plugged filter. Check the filter by removing and blowing through it. If it doesn't blow through like straw with slight resistance, replace it. Let me know.

My Jag s type is giving me a reading that says RESTRICTED PERFORMANCE and it bogs and sputters at 2.5 - 3 RPM. What the heck is going on?

Ignition coils can cause these problems, and a code scanner can tell you which one or more that are bad. If there are more than one that's bad its cheaper to buy a set.

Jaguar s-type restricted performance

I had the same problem. Restricted performance and running rough at 3000 RPM. I have an OBDII code reader and found that the problem was in the air mass flow sensor, which is just after the air filter. I pulled this out and found it was dirty and had butterfly wings in it. The last shop where I had the oil changed replaced the filter for me but put in the wrong size. Close but no cigar. Bought some *** Flow Sensor cleaner at auto store and fixed the problem. Get an OBDII reader with the ability to erase the codes. Comes in real handy.

Is it safe to drive my car

Restricted performace means the power has been cut for some reason, its probably safe to drive but needs to be serviced. Check your manual for possible causes of the light being on to determine your next course of action..

Jag s type 05. restricted performance mess. appear intermittantly

Unfortunately many things can cause this. It may just be a faulty sensor or wiring plug/socket. The jaguar engine has many sensors all of which can cause this message. Best get the cars fault register read at a garage - this should show you where the problem may lay. The fact that the fault can disappear for long periods would indicate its something minor at the moment. for peace of mind get it checked.
