Car is a 2006 base 350z manual with 92k miles. Just this week I noticed that my car would sometimes bog like there was a fuel cut for about 1-2 seconds, and then it would be all normal after that, it happens mostly in 6th gear, but it did also happen once on a 3rd gear....now starting today the car has a hard time turning on. It will turnover fine but it feels like its not getting enough fuel. It sometimes took me 1 full minute of tries before the car would start, and right before it starts it sounds like its choking. the car is also running sluggish. Could this be a fuel pump issue? I also have a cel that i've had for like almost a year before of a bad o2 sensor, but that never caused any driving problems.

 

It is so retarded to ignore codes. Bad O2 can kill the cats, plus you get used to the light being on and since it doesn't tell when a NEW code pops up you ignore it. Pull codes, diagnose codes first.

 

 

fixed it. Replaced upstream bank2 O2 and that code no longer came back. And then i replaced a cam position sensor and the no start and driveability problems are now gone and code 0345 also never came back.
