possibly the coil, it is the most common problem. what I do is remove the coil clean the spark plug and remove the coil and spark plug from the cylinder next to it and swap it clear the code and drive it if the same cylinder triggers light you the problem is not ignition , on the other hand, if the swapped cylinder triggers light you now know that you need coil and plugs.
coil or icu

when one cyl is not working right, it does not "fire"
the misfire my be caused by improper sparkplug gaps or bad injectors

Ignition coil misfire cyl 7
It is possible but anytime I have a misfire read on any one cyl. it has been a bad fuel injector. yes it very much can it can throw off your airfuel ratio causing you engine not to fire correctly..
Head bolts bad about breaking and causing blown head gaskets,Valve guides wear prematurely causing bent valves and cyl misfire. If you own one and keep getting cyl 3 or cyl 4 misfire along with oxygen sensor needs replacing, Do a compression check before spending money on parts you don't need.
It depends on the year/ 4 cyl or V6. A replacement bolt on catalytic converter for a 2010 Ford Escape with the 2.5 engine, from an auto parts store sells for aprox $500 to $600. (parts only) For a 2005-2008 the parts can be as low as $95.
