i have just taken my car (evo 7 gta) to get scanned, the error said it was egr flow control or something p0040 or p0400 cant really remember, what could be the cause of this, my guess was something like a vacuum hose come off but can not see anything come off, or.... not sure????

 

check your vacuum hoses behind manifold

 

thanks, will do
