Well I think I got some bad gas yesterday. or something. was on empty empty went and put $10 of gas in. ran fine up to the gas station. put the gas in then after about 10 mins of driving the engine started to miss and sputter on the highway. if I down shifted and got on it it it would really miss. pulled the plugs they looked fine. I have the magnacore wire, didn't see any problems. Also got a flashing check engine, but I figure that to be the mis fire code . so I did the pull a wire test. let the engine run and pull each wire 1 at at time to see if any change or no change took place. well every time I pulled a wire it got worse so that tells me fuel. so next option change the fuel filter. any idea where it's at, I never looked. I'm guessing down by the fuel tank. I hope it's not like a dealer item like everything else.
