This weekend I was waiting at a drive-thru and I thought I was hearing a sound coming from the car behind me. That car tired of waiting and pulled away.
Sound is still there! Must be mine.
I'll describe the sound as a weezing with an up and down sorta inconsistent pace.
It was coming from the back driver's side by the intake. No CEL. I was due to change the air filter, which I did and the sound is still there but wasn't as loud as that particular instance. I'm wondering if it was there all along but just didn't notice it because of all the other noises going on.
By the way, car is idling perfectly.
