This morning my van acted very strangely upon starting. Acted like it was going to die immediately and then when I slightly pushed on the accelerator (still in park), the engine raced wildly and erratically, almost dying again. I lifted the hood. There is also a loud noise that sounds like an air leak and the engine shakes! HELP!!!

You may have a vacuum leak, get a can of spray gumout, spray the vac lines and maniflod area, when the idle changes, youve found the leak! You want the engine running and spray on the outside but do direct the stream onto the hoses, if it is a vacuum leak, the engine idle will change speed, then you have detected a leak, repair the vacuum leak and see how it runs! If that doesnt do it, you may need a new idle air control valve, it's bolted to the throttlebody
You want to pay attention to large hoses like the one going to the brake booster. PCV and such.
