Been researching the net for a few hours trying to figure out what to do. Got a '07 Versa SL. My Versa has recently been acting up on me. I would drive to work get on the highway for a few miles then when I get off and have to stop, I would go to put my foot on the gas to accelerate and when it gets to about 20 MPH, it would sputter then when I keep my foot down it kicks back in (not very safe especially if you have to turn). I've tried taking my foot off and put it back on to see if that helped nope. So I went and took it in at Autozone to get a reading and I got three codes. p0030/p0130/p1148. Right now I have an rusted pipe that connects to the muffler and to the other part rusted off. I forgot the name for it and it's driving me nuts to be honest. Could that be the issue. I am 4 months away from paying this car off and this happens. I've done my best to keep it in good shape on time with oil changes and fluids, not driving like an jack ass. I'm basically live to work, College screwed me got a degree that I can't do anything with. My funds are limited and I am hoping I can get some answers from one of you folks. Hopefully someone can help. Please and Thanks.
