Hi. the air filter is in a cylindrical looking device that is connected to the intake throttle body, via plastic flex hose. it runs horizontal. you will have to un clip the plastic housing and extract the filter. i will post a picture below.

Well you didn't say what engine is in it so,I'll wing it. Assuming it's a v6, the airbox is located in the front,probably driver side. Remove the 4 or 5 wing nuts or Phillips head screws. Gently but firmly lift the top housing & slide the old filter out. Put the new one in,making sure it's in the same way as the old one came out. It can't go in upside down anyway but I'm being specific. Re-install the housing & done!!

suspect 'mass air flow' sensor or possibly a rip in the air duct from the air filter to the throttle body. this sensor, if bad, can definitely cause stalling/rough running and is notoriously difficult to diagnose, as an intermittent failure often does not throw a code to trip the chk engine lite. the sensor is located immediately next to the air filter box and has a connector of approx 6-8 wires going into it. one quick and dirty way to elicit a problem (if there is one) is to gently rap on the metal housing of the sensor w/ the handle of a screwdriver or a small light hammer. it is advised to avoid hitting the flat plastic part on the sensor (where the wire connector is inserted) since there is sensitive silicon circuitry underneath and you could potentially break something that may not have been broken already.
