Ns drove again this morning for about ~3 miles and also the check engine light is still turn off so looks favor the higher octane helped clean up the catalytic converter. I read around this on another car forum around using higher octane and looks choose it go the trick.
P0420 is likewise the code flipped for the O2 sensors. You might have had an issue with one gift contaminated. I had a similar issue through P0420 on my Subaru through 114K ~ above it. Finished up running 5 tanks v a really an excellent fuel system cleaner in each tank along with high octane fuel and also it clearing my problem. If the does come back, I"ll pull the O2 sensors and also replace them first. A lot much less money 보다 a CAT.
