Pup-pup-pup popping sound...
I know this is going to sound weird, but hopefully someone else knows what I am talking about.
My car is a 2012 2SS/RS/L99.
I was sitting in my car after starting her up and just had her in park. I was sitting and doing some things on my phone before I started my drive home. I had not heard this sound before, but it may be because I usually have the radio on. It was off on this occasion. As my car is sitting there running, I hear a pup-pup-pup-pup sound coming from the engine area. It went on for a few seconds, and ended with I can only describe as a low fart sound. Sort of the pup-pup sound but closer together and at once.
Anywho...is this something normal, or something I should have checked out? I am new to these engines, since I am a convert from Mustang GTs, and not familiar with what is "normal". It is totally stock.
Any help in solving this puzzle would be greatly appreciated.

With it being an L99, I am wondering it the AFM/VVT isn't kicking in when it shouldn't. I'd have it checked out at the dealership, have them run some diagnostics just to be sure.

Thank you. I have been a long time Mustang GT owner and was not sure about the Chevy engines. I didn't know if this was just a common occurrence, or if it was very unusual.

It's pretty tough to diagnose using spelled out phonetics on a message board. lol
I almost wonder if it wasn't the HVAC system. The HVAC systems in these cars make REALLY weird noises and everything I've read indicates it's completely normal.
