So i have been working on fixing ALOT of things on this car (85 325e) that the previous owners messed up or were just plain worn out, so i decided to trouble shoot and fix some of the smaller items i know will need attention.
I started by removing the air intake system from the TB, i was seeing if the TB needed cleaned and inspecting lines for cracks and such
Here is what i found in the big line that goes into the air boot itself
I was wondering what the hell that was doing in there, so i took it out to see what kind of difference it made if any, rpms shot up to 3k-3.5k upon start up and didn't drop, so i shut it down, tryed again and same result, i put the dime back in how i found it and it idled like it has been (around 900rpm). What is causing this? It looks like the cold start setup is bypassed as well, is that connected?
