so, i was driving to work today, and when i toko off from some lights, all of a sudden the r sounds like a wrx, that same horrible fart can noise.... its not blowing smoke, no noises from the engine, no extra fuel being used... but it does vibrate just a tad....

havent had a chance to look at it further (stuck at work all day, too dark to look for anything amiss at the moment) but before i go crawling under, any ideas on what could be up? ill just have to park it up *again* until i can find out whats going on... any help would be great guys n gals,

thanks
christophe
