I would like more info on the vehicle, as to the engine size. There are vacuum leaks on this engine, both the 4cyl and 6cyl. The injector lower seals are prone to cause this condition, but to check for this and to do it safely, is have it smoke tested with the proper test equipment. The EGR valves can also stick partially open, causing a rough idle and then a idle fluctuation and a stalling problem. Another poss cause is the idle control motor is failing. This vehicle should be taken in for service at a very reputable repair shop. If not properly diag, will cost hundreds of dollars just to "PUT PARTS ON IT UNTIL IT RUNS GOOD".
