2003 Mitsubishi Galant- 2.0L 4 Cylinder
I have a Mitsubishi Galant 2003. Recently it has began to stall out when I turn the air conditioner on. If it is in Neutral or park it runs just fine. But once in Drive and stopped it wants to stall out and does at times. It will run fine when you are going but the gas also is acting funny. When you first start to push on it, it's like it stops giving gas to the engine and the car slows or stops accelerating. The gas has done this with and without the AC on but it does it considerably more when it is on.

Rpm would go up and down from 700 to 1200 while idling and would shut off when I came to a full stop. I cleaned the throttle body and valve but problem persisted. Then I found a used throttle body with idle air control valve attached on ebay so I bought it and replace the part and the problem was fixed.

When I start my car it's fine, but when I come to stop signs or stop lights my car will putter/shake then stall. The only way I can keep it from stalling is by placing it in park every time I stop which can become an issue for not only me but other drivers. What could this issue be?

Car stalls out at stops. Slow to acceralate especially with A/C on. Went to start car nothing. All lights on.

I haven't gotten the car running like it should, when I use the a/c and come to a stop the idle speed is above 1200 ROMs, I replaced throttle body with a used one from a wrecking yard because my old throttle body was damaged or worn out, the linkage that controls the what I think is the idle broke and it was not repairable. Thinking of looking for the air idle control valve and cleaning it and see what happens next. No I am not a mechanic I just like to investigate problems and try to fix them.
