I have a 1998 Honda Acoord. My car has recently started to sputter. It did it when I started it & I just turned it off. What a some reasons that could be causing this problem? I had the spark plugs replaced about a year ago. I have also had a recent oil change. Someone suggested that I could have got some bad gas but I don't want to risk trying to drive the gas out & make the problem worse. The car is a automatic with almost 200,000 miles on it.
