Low RPM/Cold stutter

Hi Guys,

calling upon the boards vast experience to see if anyone has had this problem before. As we hit winter in Australia here a week ago the temperatures in the morning have been quite cold. I am noticing (until my car warms up) that it stutters and even backfires sometimes when trying to drive at low RPM (as in, taking off from a stop). If I give it a heap of revs its ok and once warm its ok as well.

I have a couple of suspicions, but would like to know your thoughts. Firstly, its a 97 2.5l with an underdrive pulley, an intake that I made from carbon fibre and a pedro exhaust (full)

I am thinking its either the battery starting to go (low RPM, little alternator support and cold weather), spark plugs needing to change for the cold temperature or possibly perhaps my MAF sensor?

Any suggestions!

Sam
