I have noticed, for a couple of months now , that when I fill up gas tank engine misfires when I press on gas pedal . When gas tank is less than half empty engine runs super-smooth. The emptier the gas tank the smoother car engine becomes!!

  1. Next time you fill up, try and use the highest octane they have and see what happens.
