Hello, I have a 2010 grand marquis ls and when I bought it the previous owner did not have the factory code. Is there anywhere they hid it in the car for this year? Been trying to google it but nothing is giving me a direct answer

I have a 2010 grand marquis ls. I’ve noticed that the car isn’t picking up how it should be. And kind of feels a bit sluggish. I’ve checked air filter, throttle body, and air intake and everything looks good. Is there something I’m missing? Also no lights are on the dash
