So i have a 2004 mazda 3 sedan and the gas tank makes this horrible LOUD gurggling like sound constantly no matter what. It also takes gas slowly and has a hars time starting after im done unless i rev the heck outta it. What is going on??????

 

Possibly the internal baffles have come loose. Would require replacing the tank.

 

What r those ? And i will try to post a video of it. Would the exhaust have anything to do with ot? Someone suggested that maybe some air intake was plugged and the gas tank was sucking but i dont know
