To understand the problem with your car, you must first understand that when you are pressing down on the accelerator pedal with your foot, you are NOT "stepping on the GAS". You are actually stepping on the AIR. If you are having to open the accelerator in order to get the engine started, it is because the engine is not getting enough air to start on it's own. When you let up on the accelerator, you are shutting off the air.
It is the job of the Idle Air Control (IAC) solenoid (or motor) to allow enough air into the engine so the engine can idle when the accelerator is closed.

You MOST LIKELY have a bad IAC.

SOURCE: starts but will not stay

IT SOUNDS LIKE YOUR CAR IS NOT IDLING.CLEAN THE THROTTLE BODY AND IDLE AIR BY PASS BEFORE ,THEN I THINK YOU SHOULD TAKE TO A DEALER TO RESET ADOPTATION AND RESET YOUR IDLE. I DON'T KNOW WHY BUT GEMS VEHICLE DID THAT FROM TO TIME.(1996-1999,PRE BOSCH)

2006 golf starts but soon rpm drops then stalls. will start again but soon stalls

I had a 78 rabbit did the same thing. It was the fuel pump relay. The connector was under size and burnt up. When you star the car on the old Rabbit the pump runs off the ignition switch. Once it starts the relay needs a pulse from the distributor to let it know that the car is running and keep the pump running after it starts. If not the relay times out and pump stops pumping gas. Its for safety so if in a accident and the engine stops the pump wont pour out gas

A/c smells funny it seems like the clutch is out

Is system blowing cold air? if low gas system will blow warm and smell, When was the cabin filter last replaced, the cabin filter is used for inside air, make sure its clean,

I would start by having the system checked to make sure the gas is full and dye added so if system goes warm again the dye will show the leak.
