I recently purchased an 06 Lincoln LS with 130k miles for my son. I believed the seller when he said theres nothing wrong with it. I felt like it was misfiring a little but since I drive a Mustang I thought maybe it was the cams loping. Well its been a month and I have replaced a water pump because of overheating issues, which wasnt a big deal to replace. Make sure you clean the coils on radiator because this one was dirty. Then check engine light came on and i gave me p0452 and p0420. well I replaced coils and cleared code p0420 and let me tell you this car is fast. Now Im doing some reseach for the p0452 which is the evap system. I dont have preesure on the system. I got the car at a good price and the parts I have installed weren't too pricy so I am still happy with the deal. I will try and post pics later. This site has been very helpful. Keep up the good work.
