I get a popping noise every time I shut my car off. Doesn't matter how long it's been running for, it always does it. Sounds like it's coming from the throttle body but I can't tell for sure.

Anyone else have this noise?

BTW- Dealer said it was the throttle body blade shutting...

Stupid questions: Do you have a CAI? Does it sound like a puff of air?

If not, I'm way off base and of no help.

lmao. i know exactly what your talkin about. kinda like the car is sighing when it finally off. lol i thought it was the fuel pump or something cause i always heard it from the back but its normal i would assume.

JP, I know what sound you're talking about, mine makes the same noise with the CAI

The car is bone stock. I'll post a video later today.

mine does it ... i think its just excess pressure from the intake or something pushing back out then the butterfly popping closed ...

but it has done it as long as ive had the car, only more noticeable when i installed the CAI ...

i also happen to be getting out of the car when i take the keys out, and the door is almost always open before turning it off ... but then ... i have a ritual thing and im tall as **** ... so getting in and out is an adventure in and of itself ...


my car probably when i get in and when i get out ...

Good to hear guys. I won;t be uploading video since a lot of you seem to be talking about the same thing.

Thanks
