Hello everyone, i replaced my old IACV that was stuck open with a surplus one i found and idle went from 2000 down to 900, but when i turn the ac on it drops to 500 and stays there.

The hex screw at the back is halfway out when i got it and ive seen online that it was a way to adjust the airflow for the IACV so i just wanted to confirm before i start to tinker with it or buy a new one.

For reference, its the type that doesnt have the coolant lines on the bottom so i dont think its a vacuum leak. It was also just newly cleaned.

Stock photo for reference since i can't take it out again yet but it has the same screw as the picture. Thanks in advance.

My e36 is too loud for my taste since the previous owner put a chambered muffler thats basically a straight through that offers very little sound reduction.

I have one of these on my honda civic and it both significantly reduced the drone and made it noticeably more quiet. I want that for my e36 and I wanted to buy a muffler that i know works.

Both cars have 2 inch outlets and a single exhaust pipe so I'm thinking it would work but I just want to ask if anyone has any experience with this or if anyone knows if there's something that would stop this from working. Or is this a "if it fits go for it" situation.

The car already has a resonator and is an m43b16 engine if that's relevant. Thank you in advance :)
