All a donut gasket does is provide a seal between your exhaust and your manifold. If anything you may get better mileage because there is less restriction on your exhaust. The bad part is you may get some fumes in the passenger area. ==Another Answer== A bad donut gasket could in fact cause these symptoms. It will allow excess oxygen into the exhaust stream, tricking the oxygen sensor into thinking the engine is running lean, making it add fuel and make the engine run rich. This will hurt fuel economy and power.
