Once you get misfiring like that, the plugs can get blackened. This can lead to more misfiring. If you are doing highway miles the plugs would burn clean. If you are doing short city trips, this could be a contributing factor.
When you start the car, switch ignition on, and wait a few seconds before cranking. If you have the radio on, the noise of the power antenna will mask the sound of the fuel pump getting up to pressure. You can listen for that.
Techron concentrate will help clean the carbon out of the combustion chambers, and I am suspicious that your injectors need cleaning.
If that does not help, I would pull some plugs to see whats going on inside.
