Hi im new to the scooby world, wish i'd bought one years ago now! Can anyone help please? Ive got an '03 bugeye wrx and now its started making a slight hissing noise under acceleration and the engine management light is on all the time. Any ideas???
Any info or advice greatly appreciated

 

It could be an air leak check all of the pipes to dump valve ect ect ect

 

Ive checked all the hoses and pipes that I can see and they all seem ok, cheers for the advice. Looks like a trip to the dealers......
