Smoke tested the car yesterday, found 1 leak and it was from the diaphragm on the bpv which TJ @ DT told me is normal at very small quantities which is what it appeared to be. So no pcv/vac leaks, what next. Anyone have any ideas?!
Thanks for the reply Jerry. I had started to have a suspicion of it being an o2. In theory it shouldn't be the secondary since the only reason for it is to measure a catalyst deficiency. I think my primary one is going though. Was going to swap them around and clear the code and see what happens. I'll update which my finding!
