need help figuring this out. started the other morning out of nowhere when i accelerate it sounds muffled but only when i accelerate. when i let off the gas and coast its fine no noise. im also getting what i think is a loss of power and terrible gas mileage. averaging around 10-12mpg here lately. ive checked the o2 sensors, cleaned air filter, exhaust doesnt appear to be leaking and no odor from exhaust any ideas?
