Have you had a lot of rain or power-washed under the hood lately? When is the last time it has had new spark plugs, spark plug wires, distributor cap, and distributor rotor? The 3 cylinder engine is very sensitive to misfires, it sounds like you have a multiple misfire condition. I would recommend checking the wires, plugs, and distributor cap. If you find moisture in the distributor cap then you have most likely found your issue. Let me know how it goes.
