Hey guys I have an idea... Have the dealer check your gasoline for rust. I have a 2004 auto and my car started running rough at stops and I took it in and it took the dealership a week to finally figure out there was rust in my gas. At first they thought I had pumped rust into my gas tank... then they figured out the tank had rusted and blown rust throughout the system! Try $2,500 in repairs that was not covered under warranty because they said I pumped "bad gas" into the tank that caused it to rust. However, I'm wondering if they gave us a bunch of bad tanks???
