good discussion here peeps. I finally got my o2 sensor in the mail and swapped it out last night. It's been raining so haven't had a chance to drive the car yet, but I reset the code and revved a few times, and it hasn't come back.
just watched this video. It seems pretty interesting. It looks like around $1350 for using oem fly wheel. No price shown for the aftermarket version.
I wonder when we start to see US distributors offering them...
An update.... this morning while cruising to work in 6th gear I went WOT briefly and got these codes... p0300 p0302 p0304
Since they are all on the same bank 1 , I'm pretty confident its my upstream bank 1 o2 sensor.
I was also logging and will review the fuel trim activity in a bit.
Random misfire at high rpm... p0300
Changed spark plugs
Going to do cat deletes tomorrow w big daddy defoulers
Did some idling in the driveway and took some live readings of o2 sensors.
I thought it was strange to see some negative voltage
