Hello, new member here, joined in order to get some help with an issue I'm having on my 2011 Mazda 2. It has about 130,000 kilometers on it. The Fuel consumption seems to have almost doubled. I've checked for dragging brakes, all fluids are good, intake manifold vacuum is strong, sprayed carb cleaner around all vacuum lines even while monitoring fuel trims. Long term fuel trim remains -3.11% and short remained at 0.00 while idling. New plugs and air filter. NO ENGINE CODES. throttle response is a little laggy sometimes but not consistent enough to be relevant. ANY help is greatly appreciated.
