My Escape had the same problems I am reading about - on trip home from upstate NY to LI my Escape felt like it was running on 4 cyl. Check engine light came on. Made it home but next day died and all lights lit up. Got it to a mechanic - said needed to replace all Coils - $900.00. I had it towed again to my mechanic and he said 4 coils are bad but TSB says to replace all and computer may be fried. I now remember that my backup sensor has been going off for no reason - cleaned off sensors. My mechanic can't guarantee that computer doesn't need to be replaced and doesn't want to start work until he finds out if there is a recall or warranty of some sort - since this is a MAJOR issue with 2005, 2006 Escape and Mariners. I am now out of car for the week, can't afford to rent car and pay for repair. I wish I had looked at this website before my warranty ran out - I would have renewed it.
Can you help me? Service Mgr was not available at the 2 Ford dealerships I have had service at.
Do you
have the same problem?

ARTICLE BEGINNING
ISSUE
NOTE:This article supersedes TSB 05-11-1 to update the Service Procedure and Part List.

Some 2005-2006 Escape/Mariner vehicles 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 spark plugs causing RF interference with the powertrain control module (PCM), resulting in damage to the PCM and COPs.
ACTION
Refer to the following Service Procedure to correct the condition.
SERVICE PROCEDURE
Connect the Ford Integrated Diagnostic System (IDS) service tool to the data link connector (DLC). Identify the vehicle and perform a key on engine running (KOER) test.
If only one (1) coil circuit primary DTC (P035x) is present, follow Procedure A.
If there are two (2) or more coil circuit primary DTCs (P035x-P035x), follow Procedure B.
PROCEDURE A
Remove any spark plug and inspect for a 2-digit date code (Fig. 1). If the date code is not present, replace all six (6) spark plugs.
Continue with normal Powertrain Controls/Emissions Diagnosis (PC/ED) diagnostics for the DTC.

PROCEDURE B
Remove any spark plug and inspect for a 2-digit date code (Fig. 1). If the date code is not present, replace all six (6) spark plugs.
Replace all six (6) COPs.
Check PCM internal coil driver functionality by running the Oscilloscope Escape PCM Driver Test available on IDS version B58 or later.
Using IDS select
Toolbox.
Oscilloscope tools.
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.

Replace PCM only if coil driver funcionality fails in the oscilloscope test.
Program the passive anti-theft system (PATS) keys if PCM is replaced.
If the procedure has not corrected the condition, follow normal PC/ED diagnostics for DTC.
