Report: Ignition Misfires
Ford Escape Problem
Engine Affected: 3.0L V6
Average Mileage: 123,888 mi (55,000 mi - 200,000 mi)
The common problem for ignition misfires are ignition coils going bad. Replacement of the bad ignition coil is necessary. These should be fixed as soon as a problem is detected. Otherwise the misfire can cause damage to other components.

I have replaced 2 of the 6 and now another one has gone bad.

2 coils were misfiring and 3 coils were cracked.
Ignition coils have been a continued source or aggravation on this vehicle, so far have replaced 3 of 6. Fortunately 2 have been on front of engine easily accessible, 3rd required removal of intake manifold (not complicated, but time consuming).
I just had three coils replaced for a total of $420.00 (knew the mechanic). My truck still sounds very loud, but is running much smoother.
Starting at 60,000 miles I have had a misfire code for one of the coils on plug (V6) every 20,000 miles or so. At 75,000 miles I had another one that I drove too much before repairing and it plugged up the Catalytic Converter - you'll know because the car will be slow on acceleration and very poor on fuel economy - 80,000 mile warranty, but the dealer will fight you on it since the exhaust manifold integrates three catalytic converters and the job runs the risk of fouling the muffler also.
I have replaced 5/6 coils and all spark plugs twice. This last time I did the job myself and did not go OEM on the COP - wait and see. It has been a $600 dollar job at the shop - if the coil is in the front - DIY - If in the back - consider paying the mechanic as it is more time consuming and really requires a haynes or chilton manual to do it right.

Have replaced 2 coils so far...very annoying and expensive to do each
