There is no reset for the oil pressure light. If you have sufficient oil pressure it is off, if you have low oil pressure it is on. If it is on, STOP driving the car until you find out why it is on.
The oil light is a red warning light that is telling you that the engine oil pressure is low or non-existent and to stop. Severe engine damage will occur if you continue to drive the vehicle. I would suspect you have already done serious damage to this engine. It is not accelerating very well because it is dying from a lack of lubrication. Remember RED means STOP.
