2001 E46 330i lack of power and rough idle

Hi guys,



Im writing to you, since noone here has an idea what to fix/change in my car to make it run like it should...



After a night, when I start the engine it idles at around 100-200 rpm, knocks, sneezes and produces tons of sounds i cant describe in english :P

After a while [10s] it starts to idle at 800-1000 rpm, but steel it coughs every 3s

Check engine light is on, it says system too lean bank1, bank 2

When you accelerate the car doesn't go smooth, to be honest it rides like a 320i, not a 330...



What I've done so far:

- disa valve checked

- lambdas changed

- got my MAF checked, interchanged with two working cars. The cars run OK on mine, so it doesn't seem to be a MAF problem

- exhaust camshaft position sensor [was a bit better for a moment]

- engine compression is around 12,1 on all cylinders

- fuel pressure 3,1bar

- I have no idea what it's called, but it is responsible for reducing gas pressure in oil compartment... changed new from dealership



Still the car runs like sh*t, makes me pissed



Has anyone of you had similar problems?



We have also a suspect called... Vanos... hope it isn't it
