Hi,

i have a 1995 v2 wrx, everytime i kick in the turbo at about 5000rpm, it starts to splutter , iv changed a coil pack as 1 was craked, spark plugs and fuel filter but im still having the same problem,

today i checked my dump valve has a leak in the pipe, and the airbox pipe has a big whole in it as in sumat was ment to be in there,

could that be my problem to splutter each time turbo kik in

 

If the hole in the induction pipe is after the air flow meter then yes it could very well be the problem as the ecu wouldn't be registering the air through the hole that is drawn in.

 

sort out the air leaks and everything should improve

 

Also what fuel are you running your car on?
Also is this a wagon or saloon?

Tony

PS, wrx's dont have versions, just MY's

 

air leaks sorted, but still pulling back, could it be boost solenoid need cleaning,if so how do i do this, and im running shell optimax vpower
