I have a '98 Honda Civic, which is parked outside overnight. Over the past couple of weeks I've started to have problems after a night of rain and cold temp (about 0 degrees C).

In the morning, when I reach the stop sign at the end of my street, the engine really slows down, almost like it about to stall on me. If I continue driving the 'check engine' light starts flashing. Once the car is warmed up it runs normally... until the next night of rain/cold.

I haven't checked the diagnostic code yet. I'm wondering if this is a common problem?

thanks!
