Hey guys im new at posting on forums but i just wanted to ask a question. im 19 and i know enough about cars, but i just bought a 2004 3.8L V6 mustang and i hear a weird vacuum type sound coming from the engine at idle and low rpm. i had a Mitsubishi Lancer and i knew eveything on that car, but this cars engine is like rocket science to me. I searched up what the sound may be and alot of people say its the IAC Valve that probably needs to be cleaned, but idk what it could be. It could also be how the car is supposed to sound because i never had an american car before. is this sound normal?

best thing you can do is try to make a decent video of what you think the problem is. as of right now we have no idea.
