Yesterday evening I drove, sudently the check engine light comes on. I feel that the engine is loosing power, the car is rolling arount 50MPH. I started to steer the car to the side of the street, after rolling about 5-10 second, power came back, and I was driving with check engine light. The car drove as before, smooth, normal, I could not feel any change. This morning the check engine light is off, the car drives like a charm. This happened to me about 3 times in the last 3-4 months, I am waiting until the car brakes down so I can fix the problem... I am wondering, anybody has some suggestion? Thanks for your help, Gabe
