hey well the other day my check engine light went on. i looked at my engine and the coolant was low so i added coolant but the light didn't turn off so i disconnected the negative batery terminal and put it back on and the light went off. now, whenever i reverse, the engine sounds like it's on the verge of stalling and when i accelerate in second and third gear, the car jerks. can u help me?? thanks.
