"Btw, we use our ears to listen to booster leak"?
Front mounting flange and pushrod area inside cabin.
@Xulfiqar
Ok, Can this leak in brake booster also affect fuel consumption, lean condition?
Brake booster front mounting flange is the marked rea in photo? It is , then what to do to fix leak there?
I check her, both are alright but yes there's a leak I don't know where
@Xulfiqar please see this
If you have a vacuum leak there, replace the brake booster, the pushrod seal has let go
Also change the master cylinder as its rear seal has leaked
I have been searching Google and YouTube for p0171 code and did everything except thorough exhaust leak check.My car is Nissan dayz 2014.Checked leak in vacuum through water. Replaced fulepump and filter.Replaced maf, map and upstream o2 sensor. Still no change. Still I'm getting p0171 code. History:I did cat clean from catclean at share Faisal. Since then I'm getting this code. I tried everything. I'm based in Karachi can someone recommend anyone or a possible solution.Thanks
Make sure:
1) Air cleaner assembly is seated properly.
2) Gasket rings for MAF, Throttle body are installed.
3) Check for vaccum leak in brake booster.
I think Its a very minor leak couldn't find a specialist who can check thoroughly. Can you recommend anyone in Karachi?
Assembly seated properly checked. I have changed maf and throttle body placed perfectly. Hoses/pipes looks fine to me.
In Karachi go to Jamil Autos@capsat can guide about the location/area
Any brake service done recently?

Removed the cat, detached the O2 sensor Acid mixed with soapy water.Filled in the cat (after blocking holes at both ends, with clothe-tape)Shakes it thoroughlyRemoved the tape and pressure washed
