Chances are it had oil on it @ some point and it now has a small hairline Crack, the easiest way to Check this is to Spry water on it with a bottle Sprayer.You should notice a missfire @ this point when running the Engine and since it it is a coil the Plastic covering will burn and smell also, Check the Wire's to the Spark plugs as these are Probably the original fault.if the Electrical charge is not getting to the Plug then it backs up in the Coil.which will cause it to over heat and crack

Swap the coil pack with another cylender. If the error code follows the coil pack then replace the coilpack.

do a compression test, you may have a bend valve , I'm assuming its not getting overheating so I don't think its the head gasket..a compression test can give you the answer..hope this was very helpful...thanks

SOURCE: 02' Ford escape 6 cylinder:

Although you say you have coils misfiring, it sounds like you are not sure.

Trade the coils on cylinder 4 and 5 with coils on 2 and 3. Erase the codes and try to run the engine again. If the misfire code comes up on 2 and 3 this time, the coils are definitely the problem. If the code comes up for 4 and 5 again, there is something else besides the coils that is causing the misfire on those two cylinders.

Things to check: sticking or faulty EGR valve, vacuum leaks on intake manifold gasket near or between the runners for cylinders 4 and 5, clogged fuel injectors, a bad ground for the powertrain control module (PCM or computer), wiring problems to the coils.

ENGINE MISFIRE

There are few possibilities that can cause engine misfire issues. It can be issue with spark plugs or faulty spark plugs. Also get the compression test done for cylinders. If any of cylinder shows low compression then required, then that particular cylinder will cause misfire.

Also get obd codes scanned, the error code will let you know which cylinder is misfiring or all cylinders are misfiring.

Error code P0306


The DTC P0306 - Cylinder #6 Misfire Detected means that the the car's computer has detected that one of the engine's cylinders is not firing properly. In this case it's cylinder #6.

Symptoms may include the engine may be harder to start, the engine may stumble / stumble, and/or hesitate or other symptoms may also be present

A code P0306 may mean that one or more of the following has happened:
Faulty spark plug or wire
Faulty coil (pack)
Faulty oxygen sensor(s)
Faulty fuel injector
Burned exhaust valve
Faulty catalytic converter(s)
Running out of fuel
Poor compression
Defective computer

Some possible solutions, if there are no symptoms, the simplest thing to do is to reset the code and see if it comes back. If there are symptoms such as the engine is stumbling or hesitating, check all wiring and connectors that lead to the cylinders (i.e. spark plugs). Depending on how long the ignition components have been in the car, it may be a good idea to replace them as part of your regular maintenance schedule. I would suggest spark plugs, spark plug wires, distributor cap, and rotor (if applicable).

Otherwise, check the coils (a.k.a. coil packs). In some cases, the catalytic converter has gone bad. If you smell rotten eggs in the exhaust, your cat converter needs to be replaced. I've also heard in other cases the problems were faulty fuel injectors.

Hope this helps (remember to rating this answer and leave us some testimonial comment)
