Why does my car sputter when coming to a stop? on 1994 Geo Metro

Hello, So, I have a 1994 Geo metro XFI with 47,000 original miles. It's beautiful. It is a 1.0L 3 cylinder engine.

It does have a bit of a rough idle when coming to a stop. It has a manual transmission. Say I'm coming up to a red light and have to stop a little faster than usual (or sometimes stopping normally) I downshift 4 to 3 to 2 and then into neutral.. when I get to second gear and put it into neutral, the car sputters a bit like it wants to stall, but it doesn't.. it recovers.

New on the car: new spark plugs, distributor cap, wires, air filter, oil change and filter, and hoses.. there doesn't appear to be a vacuum leak anywhere. I'm really at a loss here! Many thanks!
