My o2 sensor arrived and i attempted to change it today... fuarkk what size spanner is it? my toolset only went up to 19mm and tried vice grips but no luck. had to re-clip it and leave it. forgot to disconnect battery before as well. it's on pretty tight, any suggestions? can i spray wd40 on that area?
Get a shifter, 18inch 20inch are big enough. Shifter needs to be on tight and just needs a bang and it'll come off.
Yea you can spray wd40 there. Just dont slip and strip the bolt lol

There are slotted sockets you can buy. Theres a line on the side of it which enables you to run the wires through it so you can get the socket head onto the sensor. They're about <$10~
Mine came on at 400 last tank. Charlie u still getting shit fuel economy after new o2 sensor ?
Unbolt ur cat and have a look, mine was blocked/melted causing shit economy
