It could be a a dirty injector that is sticking every now and again. Try running some injector cleaner through your fuel system or take it to a shop and let them service (clean) the injectors.

i used seafoam in the tank with injector cleaner every oil change it never has done that again. it sounds like dirty fuel or crud some where in the fuel system causing a rough start up. i would clean every thing and check the front three plugs just to see if it is getting ready for a change it is just my opinion to check.

My wife's 3400 powered Impala does that sometimes for the first couple of seconds after starting it. It's got a lot of attention (just for good maintenance) but I can't find the cause.
I've done:
- Air and Fuel filters
- Plugs and wires
- New upstream O2 sensor
- Swapped the ICM and coils with known good ones
- Cleaned the MAF
No change. I'm not worrying too much about it, as it is not throwing codes and runs perfect after it starts. Granted, I'd love to know what's the cause.
