Title: 2.0 acceleration problem
Post by: danzigfan on 03 September 2013, 14:53:36

Hi guys, it has been a while from my miggy's last problem but a new one appeared - it's really PITA.
When changing gears up and flooring, it doesn't accelerate instantly, feels like there's something choking the engine for a moment, only after a second it starts to accelerate.
There's also a silent whistling sound coming from engine bay - it can be heard with windows open when floring it - like there's a turbine suction. Possible air intake leak somewhere?
Can anyone help me with this one?
ICV was cleaned today, also throtle valve. Car is manual.

I ahve seen the flex pipe from the MAF to the throttle body split, this would cause hesitation when flooring it and can also account for the whistle sound.

But does sound air leak related

only loosen part was this small plastic on flex pipe, added some sealant arround it, but no difference.

Exactly, but only when low rpm, it's fine in higher rpm.
And it's idling fine

Throtle body double cleaned, all pipes and hoses too.
Going like a dream now, makes a big difference  :y
