These Are The Codes I’m Getting Can Any One Tell Me What they mean. Anytime I start the car the check engine light is on and I drive for about 3 miles and restricted performance pops up driven the car several times and it jerks when I get to a certain RPM and then it catches gears and rides smoothly any answers here?

Welcome to the forums Mosauce,
Good to have you with us.
Starting at the bottom of your list, you have missed a number and it should read P1111 indicating all OnBoard monitoring tests have been completed.
P0171 and P0174 indicate lean mixture
P0300, P0304, P0305, P0306, P0307 and P0308 are misfiring - the last number is the cylinder
P1316 is a consequence of the misfiring and indicates excess emissions
This same scenario has been a frequent topic on the forum and I don't intend to discuss possible causes here in Intro forum. Follow this link https://www.jaguarforums.com/forum/xj-xj8-xjr-x308-27/ to the X308 forum for help, advice and information. The 'HOW TO' thread at the top is a good place to start for information on regular issues. You can also use the US Central Region forum by following this link https://www.jaguarforums.com/forum/us-central-36/ to find other members in your region.
Please read the guidance for new members ( https://www.jaguarforums.com/forum/n...ned-up-241802/ ) which answers many of the most frequent questions about getting started.
Enjoy the forums.
