I had this funny sound in the car & check engine light was on, took it to my local mechanic & he said diagnostic code P0307 & P0316 (engine misfire code). Please tell me what this means & how much will it cost to get it fix.

2003 Lincoln Aviator Question: trouble code
Bret Bodas February 04, 2010, 13:13Master
Your engine has 8 cylinders, and when one or more of the cylinders are not working (firing), this is called a "misfire". A cylinder can misfire for several reasons, failed spark plug, ignition coil, fuel injector, vacuum leak or internal engine damage.
A shop will charge a fee to diagnose what is causing the misfire, this normally will run about 1 hour of diagnosis time, then they will present you with a revised estimate for the needed repairs.

They have extended the warranty on the coils from 50000 miles/4years to 120000/11 years cuz they know all about this debacle.....the computer has to say they are bad tho before they will change them! By the way when your coils go they can directly destroy your catalytic convertors - I know, after much debate they had to replace all eight of my coils and my convertors at 95,000 miles!

How do I find out about this? I have been dealing with faulty coils for 3 years now. Very frustrating.

i HAVE BEEN GETTING THE PO316 CODE FOR THE LAST 3 MONTHS. I HAVE FOUND 7 OTHER LINCOLN AVIATOR OWNERS EXPERIENCING THE SAME PROBLEM. BETWEEN THE RANGE OF 40-60 THE TRUCK STUTTERS, STAULS AND RUNS EXTREMELY ROUGH. WE ALL HAVE LAREADY CHANGED THE COILS, COIL PACKS, SPARK PLUGS, FUEL FILTER, THROTTLE SENSOR, CAM SENSOR, CRANK SENSOR AND ARE LEFT WITH THE SAME PROBLEM. I HAVE ALSO HAD 3 LOCAL MECHANIC SHOPS RUN 1 HOUR DIAGNOSTICS ON THE TRUCK AS WELL AS A PERSONAL MECHANIC AND THE PO316 MISFIRE CODE IS VERY VAGUE. IF ANYONE HAS A RESOLUTION TO THIS PROBLEM PLEASE LET ME KNOW.

Same here. In 2005 I received a letter from Ford not a recall. The letter was stating that the coils could start going bad and they were extending warranty and I should keep this paper. Well all was fine for a year and of course I had forgotten all about the letter. Took it to the local Ford dealer and apparently they had no clue so I paid to have one or two coils replace. Within a month the same proplem started happening so I went to a parts store and bought 6 coils and replaced myself. Ran fine after that. Now I have had other check ingine issues since and I can't seem to go more than 6 months without having repairs. Not very happy with my Aviator mechanical issues.

Well i have had my car diagnosed for the 4th time, I have had all Coils and Spark Plugs changed, my transmission check was ok, 2 new fuil filters and a flush.....$1000 later still the same problem. Everytme 1 thing is fixed and they re run the codes there is always a new code, I now need a new computer.
