03 jaguar s-type-r restricted proformance light on
I have a 2003 jaguar s-type -r 4.2 supercharged with 110k miles, I have replaced the valve cover gaskets, with the spark plug tubes, I have put new spark plugs in they where 11$ a spark plug, I have bought 8 brand new coils, installed them, and the car keeps missing when its cold it will not even move when stated cold it shakes and turns off, after the car is a little warmed up it will run just fine, I do have two bad 02 sensors I have but have not installed them, do you guys know what the problem could be , I do run premium gas in it.

Sounds like a connection problem? With all 8 cylinders giving codes you need to look at things that are common to all cylinders. Like the fuel injection harness. Take the plugs apart and reseat them. Also check the grounds and clean and re-tighten them.
Are you clearing the codes after you read them? You have so many that you need to start over from scratch.
