Hey guys,
I got a problem with my E30 325E, The car is having problems maintaining a steady idle when cold the revs bounce from 1200rpm to 500rpm, also when driving it sometimes feels like it's leaning out, which feels like a lack of power than it kicks back in. I'm thinking it's the AFM, any thoughts? could it be something else? if it is the AFM does anyone know where i can find a good one? thanks guys.

do a thorough search for vacuum leaks. make sure all hoses are on correctly and look for dried/cracked hoses, particularly on the intake boot.

my dad's car is having the exact same problem (87' 325e as well). so far we've checked the vacuums, cleaned and changed the icv, and changed the throttle body switch. it's better when its warm now but still doesn't idle steadily during cold starts.
