See what fault codes are set, first step. It may have an OBDII connector in '95 that an inexpensive $40 code reader will plug into. The other first step would naturally be if you feel a misfire, there is always a high probability that replacing spark plugs and wires, cap and rotor will solve. I think that you would have mentioned that if you had already done that so that should be the next step actually, a good tune-up. I would also replace the O2 sensor and fuel filter.
