HAD A TUNE-UP ON MY 2007 LINCOLN MARK LT 4X4. I WANTED TO GET THE SPARK PLUGS CHANGED. TOOK THE TRUCK TO A LOCAL DEALER AND THEY CHANGED THE PLUGS. A FEW WEEKS LATER THE CHECK ENGINE LIGHT CAME ON. TOOK IT BACK TO THE DEALER AND I EXPLAINED WHAT THE TRUCK WAS DOING. THEY CHANGED THE SPARK PLUGS AGAIN. I WAS UPSET BECAUSE I CAME IN THERE FOR THE MISFIRE IN CYLINDER #2. THEY ACCUSED ME OF TELLING THEM I WAS ACCUSING THEM OF FRAUD AND NEVER CHANGING THE PLUGS. THEY TOLD ME THEY REFUSE TO DO ANY MORE SERVICE FOR ME AND TOLD ME TO PICK UP THE TRUCK. STILL HAD THE CHECK ENGINE LIGHT ON. AS I WAS TRYING TO FIGURE OUT WHAT I NEEDED TO DO WITH THIS ENGINE MY TRANSMISSION WENT OUT FOR THE 2ND TIME. (THIS TIME NOT UNDER WARRANTY) FUNNY HOW EVERYTHING HAPPEN JUST OUTSIDE OF THE MILES OR TIME. TO FIND OUT ABOUT THE ENGINE I HAD TO FIX THE TRANSMISSION. I STILL HAVE THE CHECK ENGINE LIGHT ON, NOT DRIVING AS I NEED TO GET IT FIX TO PASS SMOG AND I LOST MY JOB. SO THE $50,000 DREAM TRUCK, THAT ONLY HAS 84000 MILES ON IT IS JUNK! I KNOW THE ENGINE PROBLEM HAPPEND BECAUSE SPARK PLUG BROKE, PROBABLY IN CYLINDER #2. HOW DOES A TRUCK THAT I TAKE SUCH GOOD CARE OF, LOOKS BRAND NEW AS MOST PEOPLE SAY WHEN THEY SEE THE TRUCK BECOME SOMETHING THAT WILL END OF IN THE JUNK YARD HAVE THESE PROBLEMS. I WILL NEVER BUY A FORD PRODUCT AGAIN! LINCOLN WILL NOT EVEN STAND BEHIND THEIR PRODUCT, CAUSE AS THEY SAY IT IS A 10 YEAR OLD TRUCK!! YEAH COME SEE WHAT MY 10 YEAR OLD TRUCK LOOKS LIKE-NOT YOUR NORMAL TRUCK, I HAVE BEEN THE ONLY OWNER AND MAINTAINED THIS VEHICLE. LINCOLN SUCKS!!!!!!!!!!!
