Have Ford Questions? Ask a Mechanic for Answers ASAP
Hello and thanks for your question.
If there is no ground pulse on those 2 cylinders then more than likely those 2 drivers in the powertrain control module have failed. Ford had a serious issue with the 05 - 06 Escape for this problem. The fix was to replace the PCM and all 6 coils. The PCM has federal emissions warranty coverage for 8/80 if you have less then 80K miles I would contact a Ford dealer. Usually the coils can also be replaced as consequential damage.
The Ford technical service bulletin number is XXXXX Mention this to the dealer if you end up taking it in under emissions warranty. If you are over 80K then I would recommend changing the PCM, coils and the spark plugs.
You can rate at any time, the thread is always available to you or any follow up.
I would need to know the part number from the old PCM and the part number from the replacement.
It isn't going to match by vin or build date but it will work if you can find that part number. I cannot do anything outside of these threads with JA customers, if I were to get caught I would be banned from the site permanently.
Order it from HERE and have Ford program it.

If you should be so unfortunate to toast your PCM like I did, This is what I can tell you:1. Replace your plugs ASAP to avoid said situation if you have an affected vehicle...(See below copy & pasted TSB)2. All PCM numbers than end in LD, LE, LF, AAD and LG all superceed into a newer "revised" PCM which is part number 5L8Z-12A650-LH... Now the number on the PCM in your car will read 5L8A-12A650-xxx, That is the Ford engineering number, NOT the part number.. Although nearly identical in this case they are not always this close of a match.3. I cannot tell you what makes LD through LG PCMs different besides programming codes, but I can tell you that the AAD PCM is for 8/2/04 and up vehicles and that the "L" code PCMs are for earlier build vehicles. This does not mean the AAD will not work for your L code vehicle, My vehicle had an LD PCM and I used an AAD unit. They are available seemingly everywhere unlike the "mythical" LD thru LG PCMs.4. When the PCM shorts out, you will lose spark to at least two cylinders as the PCM has 3 coils drivers, One driver for cylinders 1 and 2, the next for 3 and 4 and the last for cylinders 5 and 6.5. Every cylinder that has a no-spark issue will need to have the coil replaced prior to a PCM replacement or you will be looking for another PCM because they will short your new PCM. Now is the time to change your plugs since truthfully, they are the culprit for all this nonsense. For the sake of things, I would reccommend Autolite 104s, (part number APP104) I would also reccommend dishing out the extra cash for Motorcraft coils if you can afford them, otherwise go with an aftermarket coil carrying a lifetime warranty.6. Replacement of the coils and plugs is EASY work. If you have basic hand tools its a no-brainer. I removed my intake manifold and installed four coils and six plugs and had everything back together in under an hour.Here is a copy of the actual TSB:ISSUE: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
