you need coils. only buy oem. if you buy aftermarket, the problem WILL come back sooner or later.

My Q threw the same code recently smh. Changed all coilpacks with oem ones and NGK plugs. Ended up throwing a random misfire after so its at a shop now but I'll update you after he lets me know tomorrow.
