bmw 335i n55 lean code

Tripaboveall · 08-25-2023, 11:15 AM

how's it going everyone. so I've been in this battle with my e90 n55 throwing a lean code every few days and could use some help. i replaced several parts such as maf sensor, map sensor, injectors, o2 sensor, and did a smoke test with no leaks. just looking to see if anyone had any ideas of what it could possibly be and or troubles you had in the same way.

thanks

Assume you checked fuel pressure before tossing injectors at it.
