Was the new sensor oem, correct part number?
Was it installed with non sensor safe rtv?
Nah, it was definitely an aftermarket brand. Came from Repco in a plain white cardboard box, no sign of a brand name on it.
Didn't use RTV, is that something I should be doing? The sensor had anti-seize on the threads from new but that's about it. Was extremely careful when I installed it to make sure nothing got on the end of it and it didn't receive any bumps in the process.
The car is definitely running better than it was prior to the sensor failing, so fixing that little vacuum leak and the new coil packs definitely feels like it made a positive difference as well. Thanks for the help, sorry it was something so stupid. I'm frustrated that I didn't pick up on it earlier but I think its because I had been chasing driveability issues for a little while before this and it just felt like a progression of the problem I was having, rather than a new separate problem. I had only just checked 02 readings with the gas analyzer a few weeks prior and they were all looking good at the time which is why I ended up checking everything else first.
