When I throttle up and let off I'm hearing a popping noise coming from there engine. Sounds like when you pull a suction cup off of something. Should be 3.5L not 2.6L.

Hello,

Usually when you hear popping noises coming from your vehicle it is an exhaust backfire, which means that the air/fuel mixture is leaving the cylinder unburnt and is burning in the exhaust causing a "popping" noise when it combust. Is your vehicle's Malfunction Indicator Lamp[MIL] or "check engine" light illuminated?

Thanks,
Alex

No check engine light. And it's not that kind of popping. It's more like something is coming free.

Hello again,

Okay, sorry about that. My bad, I don't have the vehicle in front of me, so sometimes it gets a little confusing. Is there anyway we could get you to take a video of what is going on and upload it to the site hear so we can get a better idea of what's going on? Please.

Thanks,
Alex
