When I first start up the car in the morning it wants to stall. After that the car seems runs fine. This issue only last for a few seconds. Any assistance in figuring out the issue would be greatly appreciate.

Assuming the battery wasn't recently disconnected or run dead the most likely cause of this symptom is fuel pressure bleeding down overnight. Usually that's due to a leaking injector and is a relatively minor problem. To verify it you can connect a fuel pressure gauge to see if the pressure is holding or bleeding down. You can also figure it out by pausing in the "run" position with the ignition switch before you crank the engine. The fuel pump will run for one second, then turn off. That is to get the pressure up for starting in case it dropped a little. You can also turn the ignition switch back off, wait a few seconds, turn it to "run" again, then crank the engine. Each time you do that the fuel pump will run for one second and will increase the fuel pressure to where it needs to be.

Thanks for the info. I will give the ignition switch a try. Just to give you additional info, I Took it to the shop to have my power window fIxed, they replaced the motor, so I am assuming they did disconnect the power. Also, I had them disconnect my a/c compressor at the engine due to compressor locking up (they pulled the plug in the engine Compartment on the passenger side). Ever since they worked on the car it has been acting up, shifting hard at start up and the engine wanting to stahl at start up.
So if you think there might be another issue associated with the battery being disconnected, I would like to hear it. Thanks for your assistance on this issue.

If the battery was recently disconnected or run dead the Engine Computer lost its memory and has to relearn "minimum throttle" before it will know when it must be in control of idle speed. The engine will be hard to start unless you hold the gas pedal down 1/4". It also might not give you the normal "idle flare-up" to 1500 rpm when you start the engine, and the engine will want to stall when coming to stop. To meet the conditions for the relearn to take place, drive at highway speed with the engine warmed up, then coast for at least seven seconds without touching the brake or gas pedals.
