CEL is still kickin my butt

[sprinter119]

Once again its back cel p0170. sytem 1 bank 1 too lean. My primary 02 sensor was replaced bout 2 weeks ago, (came back on). I was experiencing boost cut so i replaced my wga with the ATP WGA a week ago (came back on and it just now came back on). My vac is 20-23 and my MAF sensor is only 4 months old. Could my non fouler be messing up or the secondary o2 sensory going bad. I am tired of resetting this thing. Please give me some ideas. If i cant find anything out anybody want a free turbop5(drunk)

ive got the stock spark plugs in, ill try colder ones, ill also try cleaning my 2nd o2 sensor. thanks for the advice hopefully it works cuz the car drives fine but code is just annoying

Could it be that its really cold here cuz it only happens if i go into boost a lot when its like 30 degrees out? (have to in order to merge onto I97) Could i be maxing out my MAF this way and then throwing the lean code, my AEM gauge reads 10.0 while in boost.

def sounds like a possibility.. is the car warmed up??

could just be a bad maf? idk..

 

[sprinter119]

Yup before i leave for work i start the car and let it sit for a while so when i get back in its nice and toasty i never boost when the engine is cold damn im hardly ever in boost ill buy some MAF cleaner clean the maf and do all the above.
