Im at a loss as to what is causing these lean codes.
so far i have:
replaced downstream o2 sensor
replaced iac (it was howling and truck was dying out at stops.)
replaced one verified leaking vacuum line.
replaced upper intake and fuel manifold gaskets.
ive smoke tested and used propane and carb cleaner. there is no leak.
fuel pressure is at 60psi running.
maf has been cleaned and tested.
where do i go from here.
