    Your O2 sensor could be bad or going that way. It will make the vehicle run as if the timing is going out. You should smell strong gas fumes, usually when at the Mickey Dee's ;) Be sure to use the same octane rating or your onboard computer will be working overtime to adjust everything due to lower or higher ratings
