Car runs good, but for past 4 days, when you press the gas, it bogs down, has no power when climbing hills or even small inclines. A few weeks ago, it was running rough, had it checked, and had a hole in a hose, then it was fine. I would like to narrow the problem down, most garages are busy until later next week. I need the car for work. Could it be not enough air getting to engine, exhaust stopped up, mass air flow sensor, air filter, fuel filter? Any help would be appreciated. I am a single mother of 2 on a low income, and need some help.
