It maybe a vacuum leak. The pcv Elbo is the first culprit to check.

I don't think I would order injectors for this issue. I don't think they are causing this problem.

i would also clean the mass air flow sensor...if it got dirty while off roadin, that could def be the culprit...had it happen to me, both banks lean, cleaned it very carefully with contact cleaner and q tip, reset codes, and ran great after.

If there is no major vaccum leaks it is for certain the MAF. They arent that expensive to just get a refurbished one from any auto parts dealer.
