Air Filter Box front elbow/boot??? Blocking air? '84 325e

So... I was getting a feel for my new-to-me '84 325e last night - inspecting stuff, learning the locations of everything under the hood - when I noticed the front tube that comes forward from the air box (connecting to the plastic panel directly behind the headlight) was disconnected from this said plastic panel. So, I reconnected it. A few minutes later I started her up and smoke was coming out of the pipe as well as engine stalling. "WTF" I said. Then I realized I smelled fuel... so thought maybe wasn't getting enough air (????) - which lead me to remember the elbow/boot thingy that I reconnected. So I disconnected it completely from the assembly (see photo). IT RUNS BETTER THAN IT has since I bought it 5 days ago.

Is this a coincidence? Air filter super dirty so needs more air coming in to compensate? AFM problem?

Thanks for any advice!!!

there could be a clog somewhere around the headlight area. all that tube does is bring in cooler air from around the headlight. with it removed, youre just pullin in alil bit more warm air
I know a lot about cars. I can look at a car's headlights and tell you exactly which way it's coming
