I had a similar problem with my '94 Mercury Cougar. In my car, I believe it turned out to be the Mass Airflow Sensor or a component of the intake system. What I believe happens is that as the parts wear, they don't function up to full specs. What you might be hearing is the air being pulled past the components in the intake (between the air filter and intake manifold). Think of it as the type of sound of blowing across the top of a bottle. You are only hearing it intermittently because the outside temps are affecting the way the components are adjusting to get the fuel mixture optimized and the mass of the air being pulled through the system. Start making note of the outside air temps when this occurs and see if they are close to being the same. Mine only happened on cold mornings as well.
In my particular case, the car seemed to run fine although I had engine ping at high rpms. I had assumed it was just the age of the car that was causing the ping but when I happened upon the intake air issues and fixed them, the ping was fixed as well. If you aren't noticing any real problems other than the noise (and this is indeed the problem), I wouldn't worry too much about it. It may never amount to anything other than a minor annoyance.

I HEAR A SPUTTER NOISE WHEN I START CAR A.M. THAT LAST FOR 45SEC. AND STOPS. IT SOUNDS LIKE IT SOMETHING TO DO WITH THE ENGINE BEING COLD?
I AM NOT SURE WHERE IT IS COMING FROM. I WILL SEE IF I CAN DETACH THE WHEREABOUTS BEFORE I TAKE IT TO A GARAGE.
THE CAR RUNS WELL WITH 125,000. IT IS A 91, AND I AM THE ORGINAL OWNER.
ANY CLUES TO WHAT IS GOING ON? I HAVE NEVER HEARD THIS SOUND BEFORE.

I was actually going to post a final reply, but I wanted to give it time to make sure no other problems surfaced.
In early April, we had enough as the car stalled while my wife was turning into our development. She was able to coast it the half mile to our driveway. We took it to our shop and told them to just replace the crankshaft sensor (they wanted to wait until it actually threw a code). Cost us about $325 or so and hasn't had the problem since. But remember, it could have been a cam sensor, too, and we wouldn't be able to get a refund on the cranshaft sensor. We were pretty sure it wasn't the ignition module.

Actually, only changed the crank sensor.
Since the car NEVER gave a check engine light, therefore, no code, the shop didn't really want to throw parts at the car, but we told them we were tired of messing around and needed to give it a try, so we had the crankshaft sensor replaced (but DID NOT replace the camshaft sensor). We guessed right because it could have been the camshaft sensor instead, or maybe both.
Cost around $300 for the part and labor. We also had them replace the fuel filter as we hadn't changed that in a while (but I doubt the fuel filter caused any of the problems).

I've since traded the car and got a new Malibu. The SES light faulted a crankshaft position sensor. That was replaced and it solved the problem.
