I'm sure some of you have discussed this before which is great because you should by now know an answer of somewhat. I own a 2006 WRX with 58k miles on it now. Its completely stock and I just recently purchased it so I'm totally new to the whole stock boosted car scene and especially the Boxer engine scene. My car idles some what rough from time to time but what I have noticed is that the rpm's do not move what so ever. Just a slight bump/shake like feeling here and there when its idling, preferably when its hot and warmed up and or driven for a little bit. Does that sound normal, is that normal, does anyone else have these issues/non-issue maybe with their car? My car doesn't smoke or anything either. Any help would be greatly appreciated.
