Why would you be stuck on the side of the road with a cylinder #4 misfire? Did the engine shut down and all you see is a misfire code?

It decided to limit my power and it was SHAKING. I couldn't drive it and it was making me think it would stall which I would not have liked since I was over half an hour away from home at this point.

That description makes me suspicious of something like the crankshaft position sensor. I wonder if there are more engine codes recorded that you aren't seeing straight off.

I pulled both pending and stored codes and that was the only one that was there. They could be hiding from me lmao. It’s going to the mechanic in a few hours so. She’ll be up and running again soon.

Hope that all works out for you. We'll be watching.

BLESS my mechanic. He is absolutely my savior. Xandra had a bad coil on cylinder 4. SO happy that this was the best case scenario for me. She will be back in action tomorrow morning! Seeing how as in the last 6 or 7 months I've had TWO coils go bad on me, I am going to do some preventative maintenance come June or so and just replace the rest of the coils that haven't gone bad on me yet haha.

She was at the mechanic last week since she had an oil leak and needed a new serpentine belt since it was squeaky and cracking. She also had her coolant system flushed and filled in prep for the very warm California spring and Summer.

All good news. You're back in the game! Thank goodness for good mechanics. Keep them close.

If you're reasonably sure that 6 new coils are working, then by the same reasonableness you should be able to expect those to run 200,ooo miles as well. Driving around with extra parts that aren't likely to be needed spends money and uses space, things that could be put to better use.

If you subscribe to the idea of having spare coils, then spare spark plugs and a couple of injectors might also be on the list, as well as other things. But where do you draw the line?

It's up to you.

I carry a spare crankshaft position sensor for the Gen 2. Fairly easy fix and it's ugly when they go bad.
