A damaged or unhooked vacuum hose somewhere near the intake, also the throttle plate could be gummed up so you will want to clean it also

Next you'll want to check the throttle position sensor, it could be faulty, then fuel pressure, , then go to your engine coolant temp sensor, this is the thing with sensors, several of them could be the problem in any combination too.
