I have a 94 Buick Century, it has 125, 000 miles, engine runs great, transmission runs great. Recently changed the brakes and the oil. Runs great except on one occasion, when it rains out. When it rains or snows, (moisture gets under the hood) the car sputters and jerks like it's going to stop. It has to have something to do with moisture getting in somewhere? Any help is much appreciated.

Check all the ignition components and also the throttle positon sensor and the manifold absolute pressure sensor-make sure all wiring connectors are free from corrosion and firmly connected-

After doing the above, it it's still a problem, get a spray bottle of water and mist the ignition coil packs with the engine running. It may start missing and if so, you'll see the spark shorting to ground. May need to replace spark plug wires and/or a coil pack.
