From sitting overnight the vehicle will fire but will bog down and die. Gave it some fuel after it was fired for about 5 minutes but would still die. Got to work finally and it would idle fine until the air conditioner was turned on, then it would idles irrartically and bog down but would not die. No lights are on, I replaced the throttling postion sensor awhile back, but it wasn't trying to die on me when I replaced it, it was just idling funny. I checked the oil, no signs of gas. Any thoughts?

Thanks
