does the car act like it doesnt want to shift sometimes?becuz if its reving up when u put it in park,u could have a bad idle air control valve.but idk not enough deatil.do u have ne check engine light on?u can email me with more detail if u like too
 
When I turn on the air the car wants to cut off or when I put it in park with the air on it revs up by itself. Also when im driving with the air on it acts like it (racing) or wants to jerk. Any ideas?
check engone light is on and it showed up that the map was bad so he put a new map on it and the engone light went off but is still acting like that when air is on, it doesent do it only if the air or heat is on.
if it is the idle air valve how much is it, i looked on auto zones website and said they dident find one for this car.
