The idle is fine and it runs great what is the o2 how do i find it

The o2 sensor is the lamda sensor.

If my emissions are a bit high, my MOT tester always suggests changing the oil and filter, filling it with shell v-power and taking it for blast up the duel carriage way.

Yea changed the lamda sensor it's running perfect except for the high c0 do you think I should change the injector
