Misfires
I recently overfilled my gas tank, didn't shut off and of course gasoline projected out of the fill hole. I then drove the vehicle which ran rough but the problem went away after 10 miles. The problem I have now is that if I put my gas pedal to the floor, I get a CEL and the engine runs rough, If I stop the vehicle, turn it off and back on the problem goes away. The CEL is for multiple misfires. I don't have the problem if I gradually gain speed. I have searched this site and there are a myriad of problems which can cause this. Where do you think I should start?

Misfires were caused by the driver's side CATS being plugged, I replaced the CATS on that side and the problem is fixed.
