Have Ford Questions? Ask a Mechanic for Answers ASAP
Welcome, I'm Chris (aka Moose). Experts aren't employees / agents of Just Answer. We are independent service providers using the Site to sell their Expert knowledge to Customers. I strive to provide EXCELLENT 5 STAR service, let me know what's needed from me so your pleased.
Your codes are for timing advance and retard issues, O2 sensor lean/rich issues. You also mentioned misfire codes on 234. Though the timing codes are for the other side of the engine. It does look like the concerns are going to be related to the cam phasers and oil pressure to them. Are you going to be doing the repairs yourself?
Thanks for asking your question and letting me try to help you.
If your confused on why or how to rate me, let me know.
I'm only paid from the deposit you've made when you rate 3,4, or 5 stars.
Follow up/Reply as many times as needed before or after rating.
My suggestion will be to remove the cams, VCTs, chains, tensioners, and guides. Use air and brake cleaner to blow out all the oil ports in the heads in the cam journals, then clean out the cam timing valve bodies. Inspect for stretched chains and worn tensioners and guides. Then replace the phasers, and any parts found worn or damaged. Do you need some Ford diagrams?
I see this alot in all different stages from not bad to really bad and in some cases a new engine needed.

Glad you got it resolved.
