I was planning on tuning the car on speed density and the truck doing random shit so i rechecked my setting for failling the maf and it was okay.
After i drove me crazy so i rewelded a maf flange on the intake pipe reinstalled the maf and every thing start woking fine i dont know whats the relation between failing the maf and the o2 sensors.
Thanks guys for the help
