took it to autozone to get the codes read and its an EVAP leakage, the CEL is on but the message "check gas cap" only shows up once every 4-5 start up...but when ever i shift the car to 4, the message comes up. already changed the gas cap but that's not it.

here is the puffing sound i hear while driving, i have to turn up the volume to mute out the sound

If you can reproduce the noise when standing still, try the old hose trick to find the leak. Remove all the engine covers & and find a few feet of old garden hose (or eq.) and put one end to your ear. Use the other end as a probe.

Just be careful of the fan(s).

Mullah88, I'm so sorry you've been so frustrated this month. While I realize you're seeking DIY advice from other owners (and I'm glad to see them responding so quickly), I wanted to let you know I'm happy to help if you decide to involve a dealer at any point. For further assistance, email me at Katie_Lucille@gmexpert.com, and I can schedule you a dealer appointment so their specialized technicians can run the proper diagnostic tests on your vehicle.

Best,

Damn Mullah, I feel your pain. Now its time to come back harder. One door closes another one opens. I had a simliar issue with my 05 N*. Try changing the purge valve. Look it up if your not sure what it is.

Lol updated, the purge valve was not hooked up smh.... Once it was plugged back up, the CEL went off and the puffing stopped
