Why does the 'Service Engine Soon' light come on after driving through 3 plus inches of snow or a puddle of water or a rainstorm?
one of the ssensors got water in it
You can drive the car but should have the vehicle checked soon as possible. BUT if the service engine soon light is flashing, stop the vehicle when it is safe to do so then shut off the engine immediately. If you continue to drive the vehicle with the service engine soon light flashing you will do catastrophic damage to the catalytic converter(s).
My 1999 Pontiac Montana would seem to "skip a beat" while driving. It then started stalling and restarting, all while driving at highway speeds. My mechanic found that an electrical cable that carried an engine sensor signal was leaning against a hot part of the engine.

The check engine or service engine soon light comes on to alert you that there is or was a problem with the emissions system on your vehicle.

If it happens every once and a while and it sounds as if it is coming from the engine compartment, I took mine into service and the service consultant said that it is the computer running a diagnosis on the engine. It should happen just after starting and driving the first tie and once and a while after.

Sounds Like Your Engine Fan Has Stopped Working, Or You Are Not Getting Enougn Air Moving Through Your Radiator. How It Works You Have A Fan That Runs When Your Engine Reaches a Tempature For It To Turn On. If You Turn The A/C On It Will Run The Other Fan For Pulling Air Through Your A/C Condensor & Help Cool The Engine Also. Have The Fan Checked. Hope This Helps
