What can cause a misfire number 3 cylinder?
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.
Can I drive with P0303 code?
P0303 is Cyl 3 misfire, not random/multiple; that’s P0300. Coils sometimes just die, but I’d check the coil and injector, all you really need is a multimeter. Swap the coil from another cylinder to 3, see if the misfire jumps cylinders. If you must drive it, unplug that injector to avoid converter damage.

Much like a slow-starting engine, misfires are caused by a coating of oil from leaky gaskets, grommets or O-rings. Give your plugs a once over, even minimal residue on single spark plug one is reason enough to replace them all.
How do you test a Subaru coil pack?
Find the spark plug wire terminals and then plug your multimeter in two of them. Make sure that both terminals are pointing directly opposite of each other. The reading should be about 12,800 ohms, plus or minus 15%. If the reading is off, then the coil pack is bad and it needs to be replaced.
Can you replace only one ignition coil?
You can replace one coil at a time or all at the same time. I would however recommend having all spark plugs replaced with the coils so you do not have to remove coils twice.
