Yea, I’ve heard that about Honda’s and it has 188k milage so can’t hurt.
Bank 2 was changed about 2 years ago so time for bank 1. I really hope this
works. Did u try checking your fuel pressure?

This is exactly what is happening to me!!! I did everything you did!! PVC
valve change, Throttle body cleaning, spark plug change…everything! I
have the P0170 code for a year, but my car is running really sluggish now,
hard to go over 60mph…gas milage is down…everything you’re saying is
what I am dealing with. I am definitely changing my 02 sensors now. I
have 2 on my 2005 Honda Accord, hey it can’t hurt! Thanks for this!!

Wow, yea same here, with the rpms. I really have to punch it to go
anywhere and forget about going over 60mph. I have an intermittent engine
light, when I get gas it tends to go off then I drive a bit and it might go
on. Can not wait to see what happens. Will post back…thanks again.
