E30 Rough Idle?

5 posts in this topic

Hey all,

My 1991 E30 320i has had a bit of a rough idle recently and I have no clue what the problem is. Where there were some vacuum leaks I've been through and changed the perished hoses, the spark plugs seem to be all good. It drives very well and I have no problems there, there isn't any hesitation. Would anybody have any ideas? 

Thanks!

Is the throttle body and butterfly nice and clean? Might be worth pulling it out and giving it a clean if it hasnt been done for a while.

Maf seems to be working correctly, auto electricians checked it. How would I test it myself? Cheers
