It's the first thing after the airbox with some wires hanging out of it.

Idle Valve and O2 Sensor
 

Still chasing my tail with this stalling issue.I am looking for the Idle Valve,and the O2 sensor.I am not quite sure exactly where to find them.I found the MAF sensor today.It did not look to dirty,but I will buy the clener tomorrowI want to make sure it's not something simple before I replace the fuel filter and the in tank fuel pump.

Well you're just wasting your time. The reason your car ran better for a little bit when you parked nose down is because the gas level was higher in the tank towards the front where the pump is. go fill your tank up to like 3/4 or more full and it will run better also. Because the rubber piece between the intank fuel pump and the pick up tube is probably almost rotted away.

It explains perfectly why when you hit the gas harder than quarter throttle that it bogs out, because its not getting enough fuel to run correctly. But hey what do I know?

Hey sounds like you know a lot more than me. I will see if I can get into the in tank fuel pump.Right now the tank is full though, and it is still bogging down.I pulled one of the wires going to the 1st injector while it was running and I heard absolutely no difference in the idle.If i do it too the other 3 it stops running.It looks like the first one is connected to the fuel pressure regulator.Before I go tearing out the in tank fuel pump maybe i should see if that's the culprit. If it doesn't fix it I can always return it.
Thanks for your suggestion

Well I don't know what combination played a part in it,but I cleaned the throttle body, the MAF sensor, and all of the hoses into the PCV trap.It was almost completely clogged.As the car was running,I unplugged the #1 fuel injector and plugged it in and all of a sudden it started working.Don't know if it will stay but it runs really well.Now onto some front end end issues.Thanks for all of the help guys,I now know how the intake system is configured on this car.Normally I am a Mercedes guy,but don't tell anyone.

Hey good job I would still check your intank fuel pump pickup hose.
