My car was stuttering when I gave it throttle and I floored it running a data log.

I mmm it sure what might be the problem. N55 with 170k miles. Im thinking spark splugs maybe. Here’s a data log and the codes that showed up. Any help is appreciated. Idk how to read the data logs. So any help with that would be awesome. https://bootmod3.net/log?id=69a3497d89fbba1d53b9a448

If its saying cyl 4 misfire, swap coil/spark plug from 4 to 1 and see if the problem follows.

That’s a great idea. Thank you. I’m going to give that a shot in a little bit.
