new to subarus need help please
 

hi guys

i have recently purchased a yr99 facelift classic shape impreza

i decided the 1st mod would be a bailey dv10 bolt on replacement atmospheric dump valve

i fitted it and blanked the resurc pipe off with a bung as directed

on taking it for a test drive i noticed a whining noise on high revs and on releasing the throttle i got the nice wooshtish noise but engine seemed to loose power and nearly stall

with car being stationary and trying it the revs became erratic going up and down for about 15 seconds then going back to normal

any ideas as this bought as a direct replacement with no mention of it causing any problems

cheers in advance and any replys apriciated

Yeah vta valves do cause problems scoobys dont all seem to like em try your standard one again for a bit should clear it self up that and vta lose some power i have been led to belive but could be wrong ?

weird how they sell them knowing they dont work tho lol

Yeah the ecu works on the air going back in the system even thou its going into the atmosphere and gets confused - from what i unders tand anyway

seen this posted before on here somewhere, think the outcome was best get rid and keep standard one. check using SN search box and go through posts, may take a while but sure its there somewhere!!!

They sell them because there's a market for people who want bling and silly noises. Not unrelated to the way tobacco companies and arms manufacturers realise there's money to be made from killing people. Welcome to the world!
