I filled my 2000 Toyota Camry up with 16.703 gallons of their regular gas. Prior to doing this, the car ran perfectly. As soon as I got a half mile down the road the car started missing terribly. When I let off the gas pedal the car would barely idle and when pushing on the gas pedal the motor would miss and the whole car would shake. After I made it home, I looked under the hood for anything obviously wrong and found nothing. The car still would barely idle and was now stalling most every time I applied the gas. The next morning, The car was still misfiring and now the check engine light is on. I will take the car somewhere today to get the engine light code checked and I'm sure I will find out that it is my gas causing this issue. I guess I will pump out this gas and replace with some from elsewhere, along with never buying from Valero again. After reading some of these previous complaints, it doesn't appear there is much else I can do.
