Strange occasional stutter at idle

Strange occasional stutter at idle
I just finished a full timing chain job, new waterpump, new thermostat, new plugs, and coolant. Oil + a bottle of Restore was done the day before I parked her for timing job. Car starts immediately, runs great, plenty of power. I've had her on various runs in town and on the interstate over the weekend since getting her back together and she runs great. However on three occasions, shortly after cold start, I've pulled up to a stop light and while waiting (not immediately after down throttle) the engine starts to stutter. Slight vibration and reduced idle rpm, best description is it's like she's starting to choke out. Each time I've dropped her in park, given a bit of throttle and she's back to normal. I had a few codes on the first startup (figured normal after being opened up and running the starter 4-5 times with fuel relay disconnected to restore oil pressure) I cleared them figuring any legit would reappear soon, but I've had no codes, and no warnings - car is running clean except for this. I feel like I've been under the hood forever, any ideas to help me streamline troubleshooting this are appreciated.

OH WHERE TO START.
Well, you could start by getting some MAF cleaner and cleaning it. Warm it up and then with your fingers give the MAF a sharp rap. If the engine stumbles, plan a going away party for the MAF.
Do you have a Scan Tool that lets you see "Live Data?" That helps you see what is happening.
