Hi. There is a TSB for your vehicle for this concern. It is quite common. You need to replace all six ignition coils and spark plugs. You may also have to replace the PCM ( vehicles main computer ). Here is a copy of the TSB.

Some 2005-2006 Escape and Mariner vehicles built on or before 10/3/2005, equipped with a 3.0L engine may exhibit a malfunction indicator lamp (MIL) on with two or more diagnostic trouble codes (DTCs) for coil on plug (COP) primary circuit faults (P0351 through P0356). This may be due to the COP and powertrain control module (PCM) reacting to radio frequency interference from the spark plugs.

ACTION:

Follow the Service Procedure to correct the condition.

SERVICE PROCEDURE

    1. If codes P0351 through P0356 codes are stored in the PCM continue to Step 2.

  2. Replace all six (6) COPs. Refer to Workshop Manual (WSM), Section 303-01B.
  3. Perform a PCM internal coil driver functionality test by running the Oscilloscope Escape PCM Driver Test (available on Integrated Diagnostic System (IDS) version B58 or later).
  4. Using IDS, select:
    1. Toolbox.
    2. Oscilloscope tools.
    3. Escape PCM Driver Test - follow on screen instructions.

       

      NOTE:THE OSCILLOSCOPE TEST TO CHECK PCM INTERNAL COIL DRIVER FUNCTIONALITY MUST BE PERFORMED PRIOR TO REPLACING THE PCM.

I can replace parts but would you recommend that a dealer look at it? The vehicle has 109,000 miles and this sounds like a defect "Radio Intefernce from the Spark Plugs"

does the dealer repair this under warranty. Almost sounds like a recall should have happened.

 

 

Thanks

 

Expert:  someguy_78 replied 3 years ago.
There is no recall and no warranty coverage. It is a TSB (technical service bulletin). If you end up having to replace the PCM you will have to have the dealer program it. If you just replace the PCM yourself and don't program it the vehicle won't start.
Customer: replied 3 years ago.
Ok...one last question. Since the plugs and COP's need to be replaced I will do that myself an dif the problem is resolved great if not I will take the vehicle to the dealer and have them replace the PCM. so if I replace the plugs and COP's should I use Ford factory parts or for example would Duralast COP's and off the shelf Autolite plugs be fine?
Expert:  someguy_78 replied 3 years ago.
I never recommend autolite plugs. They are garbage. I recommend Motorcraft plugs. You can use after market COP's.
