Could be several things. How up to date is ur SUV's maintence? Spark plugs, wires, fuel filter, Fuel system cleaning, trans flushes, etc?
Also, there is a problem on these SUV with the large vaccum line running off the PCV Valve to the back of the engine. I would def. check that vaccum hose and it's molded elbows out as well...
