My Ride: 2005 bmw 325i
Alright so Tried to unplug maf sensor, the first time I unplugged it nothing happened it smoothed out (barley any difference) than I did again just to make sure ,it puttered and went all crazy. I'm not sure if that's good or not?

I checked again for vaccum leaks, still nothing I've Tried the smoke test but this time I just sprayed it with carb cleaner on cold start(still no leaks found, even got crazy with it and started spraying the hoses and boots from top to bottom). Did see some little cracks in the upper boot, real small, the width of a infants nail maybe, sprayed those hopeing for a idle change but nothing.

I'm not sure how to test the filter element? How do I go about that?
