INFINITI G35X
P0301 and P0174 SES Light

Service engine soon light came up on my 2008 G35X. The codes were: P0301 (Cylinder 1 misfire detected) and P0174 (Bank 2 System Too Lean). I'm sure it's one of a few things, either a dirty O2 sensor or vacuum leak. Just wanted to see if anyone else has had this issue, and what the potential cost to repair is. Thanks in advance!

Get an OBD2 scanner that does real time data and check the O2 sensor for cycling issues.
