Any additional information? For the past several weeks, my 99 3.1 runs like it is ready to run out of gas. It will stutter at 10 - 20 MPH and after a while get up to speed. It seems to do this at red lights. I thought it was bad gas. Then it will pick up. It stops doing this for about a month then does it again. Yesterday, it gave me a code P0300 and it blinked twice. Any ideas what this may be? I was told to replace plugs and wires, but I have 8K miles on both.
