i have a my03 impreza wrx which often trows up a fault code relating to the tumble generator valve sticking open after doing some reserch i can only find posts on american sites sayin its somethin to do with there emission regs and only fitted to usa models????? but mine is a uk car as far as im aware has anyone come accross this before??

 

Newage WRX's (UK as well) come with "Tumble Generator Valves" designed to reduce emissions at low revs....

They can stick at times ad throw CEL's.....some people get rid of them (APS do a TGV delete kit) but fooling the ECU into thinking they are still there needs a re-map

I think Butty did a post on how to clean them
