what should i do? adjust the afm? btw i have a rough idle ... and so far i installed new spark plugs air filter and fuel filter already, and wires are only 30,000kms broken into.

My idle is like the same as this guy: Should I adjust the AFM?

btw i did drop my airbox/afm several times on grass not sure if it had any effect
My car is a 1991 BMW 318i has the m42 engine

I highly suggest not adjusting the MAF like this guy did.
I had a spare and after I swapped it with my known 'bad idle' MAF the car idled just as bad so I decided to try what this guy did.
And just like one of the responses in the video, the car idle'd smoother than it ever had during my ownership but driving it under normal driving i.e. higher revs and such the car ran like dookie.

Look for intake leaks, O2 sensor, etc.

I'll second that... Pulled my cover off and played around with my sensor, now it's weak in the top 2,000 rpm.
