I have a 2014 BMW M5. The only modification is the JB4+ HW v2 running FW V2_2_3.

I've mostly been running map 3 as I don't yet have the sensors hooked up for the BCM. It's run fine for the past 9 months, but lately I've noticed some rough idle on occasion. The past two weeks the BMW has put itself into low power mode, and throwing some fault codes.

I'm not an engine or car expert by any means. I read the error codes and did a little reading online. Forum posts I found online seemed to indicate that there is an issue with either the injectors or fuel ports?.

As my vehicle is out of warranty, I decided to schedule a service appointment for tomorrow morning with BMW, thinking that this is something they'll need to look at for me.

Before I do that, I wanted to get an opinion from the BurgerTuning experts.

Here are the error codes as well as logs from the moments it occured.

Looks like code is for misfires, I'd start with new plugs. We have a replacement kit on our site. You'll want to gap the plugs down to 0.022".

Thanks for the review and quick reply.

Do you recommend the NGK 2-steps colder 97502 or the NGK 95770? From what I can tell, it appears that the NGK 97502 is for tuned vehicles, while the NGK 95770 is for stock vehicles, an alternative to the OEM supplied Bosch ones... Is my understanding of this correct? Seeing as the NGK 95770 are globally backordered, do you have any reason that I shouldn't use the NGK 97502 in my vehicle?
