First CEL

[Kilabyte]

Hey all, got my first CEL this morning, P0300, P0301, P0306. Misfires on a couple of cylinders.

I am a little over 30k so I'm guessing spark plugs? Only mods are intakes and JB stage one box

I've cleared the code for the time being, the car drove perfect, I'm ordering plugs later today. Who has the best prices? FCPEuro?

Thanks for the help, I forgot that everyone here just gets a new car when that happens.

Can a mod delete this?

Lol, no here's real enthusiasts that enjoy working on their cars as well in here. What do you use to read the codes? 30k is about where you need to change plugs, but note that it can be the coil packs as well. Do you plan on tuning? If so you might want to consider the ngk 2 step colder

1. You posted in a lower traffic section. Try the Engine / Tuning section next time.

2. Look up the trouble codes here: https://bmwfault.codes/

Don't feel discouraged. Majority of the posters in here simply don't know enough to help, or are here to help. Most of the answers are out there, you just have to do a few minutes of digging.
