Well as the title says my 05 g35 is running lean. If I remember correctly it was p0171 and p0174. I have don't the basics spraying brake clean around the intake area and intake hoses and haven't got any change in idle. Looked at the most obvious a vacuum leak and have not found one. I was goi g to go ahead and check fuel pressure see if I have a bad pump on my hands but am unable to find a test valve for it. Hooked up a scanner to it and can see both o2 sensors indicating it is running lean. Was hoping someone had some experience with this issue I don't hang parts on cars unless I can verify it is the problem. It has a hard time starting and sometimes feels like it is missing at idle well I'm sure it's missing at idle. Any help would be greatly appreciated.
