my leon is stuttering at around 2k at 1/4 throttle. it make a sucking noise when it happens and the same noise happens when i change gear while on a decent amount of boost. Ive checked the turbo for play. fixed any boost leaks ive had. replaced lower boost pipe seals. just had new actuator on turbo.
ok so things i think it might be
in tank fuel pump it makes a fizzing noise when its priming if its been sitting for a while but its been doing that since i got it in august and ive done a full service with quantumn since then. Had the pump out n the thick pipe that goes to the actual pump from the housing is air tight but i tightened the clamps anyway.
vacuum related. i recently had problems with boost because the one way valve around the n75 valve was completelt clogged ive since then cleaned it out but i think its going both ways now. ive also replaced most of the vacuum lines but not all of them.
any help would be greatly appreciated even just a place to start would be great its got me stumped !!
