For the past year, whenever I use any non-Chevron gas, the engine shakes so much on acceleration, I think one of my tires has gone flat. I've tried alternating Chevron with Costco/Safeway, but usually more than tank of non-Chevron gas results in bumper to bumper shaking on acceleration. I'm trying to figue out if it's an oxygen sensor, fuel filter or what. I can't afford to start replacing parts on a hunch, or pay a mechanic $85/hr to track it down.
