Ford F-150 Code P0303 Causes
Cylinder 3 misfires can be caused by many reasons from a faulty ignition system, fuel system, or internal engine failure. The most common reason for this to happen is faulty or worn-out spark plug coil packs, especially if it’s been a while since you had a tune-up.

How do I know if my F150 coil pack is bad?
Common Symptoms of a Faulty Coil Pack
A rough idle.
An unexplainably louder-than-usual engine.
A noticeable lack of power.
A significant drop in RPMs while accelerating for no apparent reason.
A blinking or intermittently activating check engine light.
An active gas warning light when the vehicle has plenty of gasoline.
How do you diagnose what is causing a misfire?
Look out for the engine light or malfunction indicator light on your dashboard – at least one of these will flash if your catalytic converter is at risk of damage. A diagnosis can often be made quickly if the cause of the misfiring is the spark plugs. Worn spark plugs can be replaced easily at a low cost.
How to fix F150 misfire?
Inspect the spark plugs for signs of damage.
Use a spark plug socket to remove the plug so you can get a good look at it. The damage you see will help you determine the cause of the misfire. If the spark plug is just old, replacing it may solve the problem. Make sure to replace and properly gap new spark plugs.
What is the most common cause of a cylinder misfire?
Engine misfires can be caused by a list of faults, but there are a few suspects that occur more than others. The primary villains are simple – spark or fuel – usually manifesting in spark plugs, plug wires, the coil(s) or the fuel-delivery system.

How do you diagnose an ignition coil problem?
If you suspect the coil is dead, you can also remove the coil, plug it back in, and use an ignition spark tester like OEM 25069 to determine if the coil is firing. You can also use a multimeter to test resistance.
How can I check my ignition coil?
How do you manually test an ignition coil?
Ignition coils have two circuits that require checking; primary and secondary circuits. Connect the multimeter to the negative and positive terminals of the ignition coil to get a primary circuit reading. If the multimeter shows a reading of 0 ohms, the ignition coil has shorted and needs replacing.
