i still say lean spot also. if it goes away while driving awhile then the fuel trims are fixing it. then you shut it off and turn it back on the short term are having to fix it again. especially if he has the long term trims turned off.

 

You need to get YOUR OWN wideband on it stat!!!

 

if it says bank 2 too lean dose that mean that the lean spot is on the pass side only like the 02 intame gasket fuel injectors something around there

 

could be check all that stuff. and it would be good to log stock narrow bands to get an idea of what they are doing along with wideband.

 

Im assuming you are running a closed loop MAF tune?

 

yes........

 

change my inj and still no changes still stumbling but now it dose it for 5min or so of driving and it goes away

 

sometimes i press the gas and it seems like if im cutting the fuel completely but my boost gose up that's wearied and it only happens at low rpms half throttle the as i give it more the it goes

 

still sounds like tune probably a bad spot in the maf table. if there was a bad wire to injector or open injector you would get p200. plugged injector would be different but should happen all the time. low rpm half throttle still just seems like maf/ve table. if it fixes the the stft are working if it comes back ltft are off.
