Question about Ford Fusion
Had mechanic put it on computer to check why engine light was on and he said #6 coil was misfiring but doesn't know the firing order so I have to do the mechanics job of figuring it out

check to make sure #5 spark plug wire isn't bad,make sure you have not wired it wrong from changing plugs. You should purchase a chilton manual if you haven't already

have the crank sensor check for erratic operation. if you have done all of that then there is nothing else. and they way the computer knows it is misfiring (if it is) false code maybe and could be bad crank sensor. good luck

A P0306 code means that 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
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
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.
