Bout 3 weeks ago my car started playing up, smelling of petrol, running abit poo etc, thought it was down to the afm which I was changing (vxr one) when I went red dot, while at Red Dot they said my car massivly over fuelling, after the vxr afm and injectors were fitted.
So they backed the fueling off abit and was ok but he said it is still over fuelling a little abit.
It was spluttering slightly after dot but on way home went ok and ran perfect, half way home the emmissions light came on but still ran perfect without spluttering.
When I got home I got P0170, fuel trim blank 1, I reset the ecu and the light stayed off but smelled of petrol and spluttered again, now tonight the light has come on and stopped spluttering lol, can anyone tell me what might be the problem with this P0170 code, We have an idea that it might be the front O2 sensor as when the pre cat was put on it had seen better days but is there any other things this may be?
Cheers in advance,
