If the exhausts are a litte sootie and there's a slight petrol smell after running hard does this suggest the car is running a little rich? I know it does with a Rotory Engine but not sure with a V6 twin turbo.

If its just a little I wouldn't worry, turbo engines often do this.

My car runs rich ... it always has .. it has a JWT chip and obviously it has the same results ...

 

better than lean though :-)

Thanks guys that's great. No need for me to be concerned then.

Depends how rich? you need to do an o2 sensor check via diagnostics (conzult or Datascan even better) check the plugs and gaps too.

If the o2 sensors are gone then you will be running overly rich all the time, resulting in bad fuel consumption, performance, and with time you may wash the cylinder bores.

if theyre a bit sooty, give them a little sweep.

 

ta boom tish... i'll get me coat.
