Sometimes I go to floor the gas pedal and the car barely moves off most of the time, that is my automatic car in drive. Driving up hill is a struggle most of the time to. I have had the car at the mechanics a few times. I have had a new fuel filter/pump, spark plugs, new coil pack, air filter and throttle body cleaned lately. It drives a tiny bit better but the main problems are still there. Also the car is drinking a lot of gas to. Please, please could you assist me because I love my car and don't want to let it go.
