Fan of your youtube videos.
I have a
2001 Honda CRV with fault code P1399 and P0141.
Cap and rotor
All above as general maintenence.
I replaced the valve cover gasket and adjusted the valve lash too.
Cleared all the faults but still code present and car symptoms are
Pops/back fires when accelerating
Ive also replaced the idle air control valve but bypass the coolant hoses to it as i live in a very hot climate year round.
If you could point me to a direction to look at id greatly appreciate it.
