I thought I had a lazy o2 sensor on my VY II, The left hand o2 sensor was not going full scale as it was oscillating. On closer inspection the LH cat had been replaced so I figured At 150 Km’s most likely the sensor is getting tired or had been damaged when the cat was replaced by the previous owner. So I got a couple of bosh direct fit replacement sensors and replaced them,
Unfortunately the new sensor is doing the same thing. Jumps up and down sharply between 0.6 and 0.3 volts
I put the laptop on the computer and it shows the BLM has moved quite a lot for the LH Bank.
I pulled the injectors and inspected them and they all look clean and ok, cleaned throttle body ect, No change.
The only thing I can see is the LH cat looks a lot smaller than the RH original one and there appears to be a small leak around the base of the bush the o2 sensor screws into.
Anybody else got any ideas Where to look.
