Hi guys, I originally had the code P0100 (MAF Sensor) so that was replaced and the car ran much better, but then I had P0170 which is fuel trim Bank 1
I have tried finding leaks in the vacuum by spraying carb cleaner on the pipes but I can't find one. The garage I bought it from told me they changed the O2 Sensor but I'm not 100% certain.
The voltage on the O2 Sensor bank 1 sways really fast between 0.000-0.900 but I have now been lead to believe that this is normal(?) The Bank 2 one stays around 0.44-0.46
I also paid for a full service and a fuel filter replacement!
I have no idea and am completely clueless
