2007 S-Type 4.2 Error code
 

Hello, My name is Dave and I own a 2007 Jag S-Type 4.2. I'ts got 118500 miles on it, but still runs and looks great. Nothing like a British hot rod. I love it, but I have a couple of issues. First, I'm getting a P0411 secondary air injection incorrect flow error code. What is this problem and what do I need to look for? Second, Corpus Christi does not have a Jaguar dealership and I am looking for a good Jag mechanic. I'm pretty good with American cars, but not so much with British cars. Any help would be appreciated.
Thanks

Emissions injection issue
 

For the P0411 code you possibly have a hose or leak in your emissions air injection system this injects air into the car upon startup when cold to ensure proper ignition
