If you have a bank that isn't jumping up to 200+ on the AFR as soon as you let off the gas, there is a good chance that you have a sticky/leaking injector(s) in that bank.

Not sure if you are interested, but I have the equipment to flow test, check spray patterns, ultrasonic clean, run thermals, and high pressure leak test N54 injectors. I've probably done close to 50+ sets of injectors for different people on here and the FB BMW groups. If you need someone to service your injectors, let me know....I do it cheap, just trying to help people out and cover my time and expenses. I can get them turned around in 3-4 days or less.

If you have one (or more) that are leaking really bad, sometimes cleaning will resolve the issue, but sometimes it won't. There is no guarantee they can be fixed, but at least that way you will know if they are bad or not. Shoot me a PM if you are interested.

Unfortunately, I'm in the USA...Missouri. Probably not with the trouble or cost to ship your injectors to me. Sorry
