Put new coils and plugs in 4 and 6 and be done with it. The more you play around with it and the more times the class A misfire occurs next you will be shelling out thousands for cats they fail quick on the escapes.

 

i've had coils go bad. Just replace with new ones. My mis-fires went away.

 

OK guys I replaced the 2 coils with new. Now it was good for a day but between 75 and 85km it starts missing and engine light flashes then after 85km it goes back to normal no misses and drives properly.

 

The horse may already be out of the stable and could be too late to close the door.
It does matter what coils you put on an engine.
Ask yourself why those coils were just laying around, because they were good????
As Makuloco 2000 stated playing around with junk coils may have cost you a converter(s) problem. When that lite is flashing it's telling you have the engine looked at right away because it is in the process of ruining your converters by running rich and the converters can't handle that for very long. Misfires are one of the main reasons for running rich and some engines will disable fuel injection to the affected cylinders to hopefully prevent the converters from being ruined. In my humble opinion , I would suggest you find another mechanic/technician .

 

Thank u for the reply. I guess I should state they were used coils from another escape 04 not 03 like mine. Not sure if that matters.
They were from a running escape that was rear ended so all engine parts were decent.

My escape runs great good power no hesitation or misses until 75km then the rpm drop real low and then it misses and hesitates but after 80km it's back to normal rpm and power.

I should also say if I'm going good on the gas and not light it won't have that problem between 75 and 85 and it's only when I'm accelerating lightly on the gas.
