white smoke in the morning

If the smoke is steam, then that is normal. If you had a problem with your engine, the coolant would be running out. Is the coolant running low a lot? How about the oil level? The Check Engine Light coming off and on can be several things. The fact that it is intermittent is good. it may be just a gas cap issue. I would have the code checked. It is impossible to say if the morning smoke or steam is related to the Engine Light until I know what the code is ( there are hundreds ). Is there any smell to the smoke or steam? Does it smell sweet ( coolant) or like burnt rubber ( oil ) ? Let me know.

Did you ever find an answer to this? My car does the same thing. Engine acts perfectly fine. thx
