Hey guys,

First of all here is my mod list:

Injen Intake
COBB Charge Pipe
JB4 G5
Turbosmart BOV
N54 Downpipes

I have been having problems with rpm's fluctuating ever since jb4 and have noticeably seen rpm's fluctuating from 500-1000 after doing the charge pipe (roughly 5 days in) .

I have changed the spark plugs but not the coils and was wondering with this log if you guys can tell me what is wrong with the car. I'm putting my bets on coils with IGN1 being so random at idle and the AFR being affected by that. I'm pretty new to the tuning scene so I would appreciate some help from you guys. Thanks !


Car info : 2008 335i N54 - 140,000km
Fuel Pump changed 2011
Injectors recalled 2011
Spark plugs changed 2016 (September)
Battery Cable Recall

Have you tried to clean your vanos solenoids? That can help with idle issues.

Nope not yet but wouldn't solenoids throw some kind of code?

I did get the service engine soon light with the JB4 on map 0 and I assumed it was downpipes

The solenoids never threw a code for me.
