Ever get to the bottom of this? I’ve been dealing with this for like 2 yrs, pretty identical conditions and symptoms. Just curious If you got it or gave up. Haha.

Hey Guys,
I am still having the issue as before, but got it down to a good cadence to when the issue happens. The P0300 code appears after of driving for (30) minutes, before it did it sporadically, but after making the repairs below, it only shows after 30 mins of driving. Any ideas?
So far I have done:
Changed Plugs
Tested all coils (all were good)
Changed a leaky PCV Value (changed both just to be safe)
Replaced all (4) crankcase hoses (used Z1 hoses)
Re-Tightened all G3 pieces and hoses to be safe.
Someone told me it could be the battery going bad or a loose 02 sensor?
thx,
Brian
