Hy everybody,so i purchased my first Crown Vic, it's a 2002 model LX. I got it for a few bucks but in running condition. First issue is a code for air/fuel mix too lean on bank 1, and my guessing is that is somehow related to an aftermarket K&N air filter(came with the car).Second issue is i have heat coming in the car as long as the car does not move, when driving the car the air gets colder. I was thinking it might be the thermostat but waiting to do some more research. Thank you.

 

 

Picking my '07 up in a few days. I would say that your extra idling hot air is coming from the floor around the transmission tunnel/firewall. The vinyl flooring doesn't seem to be solid in and around that area.
