Hello, Michael,
My replies about the issue were speculative -- obd2 code can lead you down funny rabbit holes.?
You're correct about the injector ohm test re clogged or fouled. But that test doesn't account for shorted injectors, leaky injectors, leaky o-rings (which can cause misfire at load which is what you described in your original post) or mechanical issues inside the injectors. So to eliminate injectors entirely you'd need to "flow" them and look for rate/time and then drips after injectors shut off. Then use an oscilloscope to watch for the pintle "hump" in the injector's waveform -- when the injector is energized a magnetic field is created which pulls up the pintle to let the gas discharge.?Absent those tests, the injectors can't officially be ruled out as a catalyst for the misfire codes you received.
That said, I'd examine?all your spark plugs, especially cylinder 2 and 6 plugs! Look at electrode gaps.
Look for carbon tracking on the porcelain which is an indication of arcing in the spark plug boot.
Examine those boots for tears.
Always test new spark plug wires for resistance. Should all be fairly the same. Just keep in mind resistance is measured in ohms per foot. It's possible you have a couple of bad ones.
Look for carbon tracking inside the spark plug connector that connects to the spark plug.?The issue could be just that simple.
You certainly shouldn't have to replace those spark plug wires this soon. Have you checked for mice issues?
If spark plug gaps are nubs you'd have to ask why -- 5,000 miles isn't much to ruin plug electrodes unless something else were going on e.g. a harsh lean (typically) fuel condition. And for that kind of diagnosis you'd need to know and understand your fuel trims.?
Examine the coil pack for any signs of cracks, chips, arcing. If you really want to test the coil, you're going to need a multimeter (or oscope) to diagnose whether the issue is with the coil itself or the inputs to the coil. Simple to do if you have the tools and know where to hook up and what to look for -- safely. Not so easy if you're a diy'er with few tools. YouTube certainly could help you with other tests you can do. Just use caution around the high voltage and fuel.
The vehicle workshop manual would be super helpful for you. You might also consider a monthly subscription to prodemand diy (I think it's called Mitchell1 for consumers). I have no affiliation with software or manuals. They're my suggestions based on my experience.?
Last tip: Use what you can see, touch, smell or hear to validate what's working and what's not in the engine compartment with engine on and off, or even key on, engine off.
