My car has had an emissions light on the dash ever since the engine was put in the car in march.
Now it says the error code is:
heated o2 sensor circuit bank 1 sensor 1 and sensor 2.
So I'm guessing this relates to the two lambda's on the precat and cat sections of the exhaust.
I have replaced both of these sensors and the light is still up
The car idles a little low IMO. And maybe overfuelling slightly.
Although it drives faierly smoothly with no judders. Although i don't seem to get any overboost and it drops off to around 6psi at 3500-4000rpm.
Could anyone shed any light on this for me as it's doing my head in.
Could it be another sensor relating to these that is the problem? For instance the MAP sensor on the intercooler??
I have an AFM arriving brand new today or tomorrow as i found one cheap. So I will try this ASAP.
It just feels like the car starts to pull into the power band and then just backs off leaving you a bit disappointed.
Any thoughts welcome.
