Sounds like your throttle body needs cleaned out, there is a small hole (orfice) inside above the butterfly topside of the throttle body ,that gets filled with varnish,carbon deposits, take off the t.b. and clean with throttle body cleaner, buy it at auto parts store, spray can.

Make sure all your drain feeds are not clogged with debris, or take a garden hose and run water over the top of the roof panel for 15 mins.or so could be the windshield seal

I have a 2005 and the things that go bad on it is when the sensor goes off then for the intake then where the butterfly is on the intake gets dirty and needs to be cleaned it is the venturi gets dirty and needs to be cleaned and if it is a cam crank then it is the cam actuator that needs fixed you can tell if you take it off and there a screen missing it is a good sign that it needs be replaced and it is on the left side of the engine you need to understand that if it gives you a code that tells you that it is a sensor that is telling you that what the sensor looks after is bad not the sensor

check fuses

The filler vent is not working properly.

buy manual

Check the battery then try taking it to your local Autozone for a free diagnostic test.

ON your vehicle you cannot manually adjust the idle as it has the idle controlled by the ECM. The ECM analyzes data from the systems sensors and determines how much air and fuel the engine needs to run at the desired speed. If the car is idling higher or lower than it normally does then there is a problem with a component of the engine or it's control system or there may be something foreign to the system causing the problem, either way you cannot manually adjust the idle and you are most likely going to have to have a mechanic or someone with mechanical skills and diagnostic tools, read the trouble codes or datastream to narrow the problem down.
