I have a 1999 Pontiac Montana and after a heavy rain storm the service engine soon light in blinking continuously and the engine is running very rough with a lack of power. once the car warms up after a few minutes the service engine soon light remains on and the van runs smoothly again. I am thinking maybe a cracked distributor cap or an emission problem . any thoughts would be appreciated.
