Rough starting this fall / Winter

[Pdwight]

My Boxster has always run like a mean watch, that being said I noticed this year on cold starts it is rough. Usually in the first 10 seconds it will almost stall and then catch backup....no codes. I do make it a habit of never racing the engine especially when cold and always give the engine about 20 seconds to idle up on cold starts.....at least this way I feel the oil is getting moved around better before placing a load on the drive train. I suppose it is time to remove and clean the MAF...any other suggestions ??

Thanks in Advance
