Last year I was getting a shaky engine at idel and very rough running and then it quit and wouldn't start. Dash lights said "Restricted Performance", ABS, Coolant Low, orange and red bars.

Jaguar dealer in Plano Texas checked for vacum leaks (non found)
Replaced the throttle body (slight change)
Then replaced one ignition coil (big change, ran smooth bur every now and then "Restricted Performance" would pop up then then go away.

Today I got the shaky engine again? Dash lights said "Restricted Performance", ABS, Coolant Low, orange and red bars. Car will restart and run but it shaks and is under powered. What do you think?

Hello
Thanks for the donation

So when you replaced one coil pack it fixed the issue for the most part, correct? I suggest replacing the other coils as well. If one is faulty, the others are probably just as bad because they all have went through the same mileage as the one that was replaced.
