This has happened all of a sudden?
It is sounding like it is starving for fuel...
First we will check for bad fuel. A GOOD Gasline Antifreeze can get the impurities and water out of the Gas. Get a bottle and pour the whole thing in the gas tank, bounce the car around to mix it with the fuel. Start it and let it run for a little while so see if it smooths out. If does not help then look at replacing the fuel filter as it may be clogged.

The problem sounds intermittent, if you put volt meter on the battery while it is at that 19volt mark/reading(on the gauge cluster) you will be able to see if it is true. If your alternator is really charging over 16volts the lights should be getting brighter then usual and/or they are burning out. Find out ASAP, if the alternator has a defective voltage regulator, it needs to be replaced. Prolong use will damage components.

Check out your cold start choke. It is designed to cause your fuel mixture to run "rich" until it warms up. It is basically a heat sensitive coil that reacts to heat from the exhaust manifold.
