I have an 03 WRX with like 45K on it and the car runs really good, but it has an idle that seems like it wants to shut off once in a while. The idle will be completely fine and then drop down like it wants to shut off. Has anybody else experienced this , or does anybody have any suggestions. Any help would be greatly appreciated.
The dealer says that I dont need to change the spark plugs until like 60K , but I might want to change the fuel filter. Does this sound right , and is there anything that I can do ( tune up wise ) to make it run smoother???
