So I have 2003 350Z completely stock except for exhaust and I was driving it fine a couple weeks ago then I come to start it and it dies a second after starting. I have swapped the maf redone the all the gaskets for the plenum checked for vacuum leaks and couldn’t find any also checked my fuel pressure and fuel pump and everything was fine. The car is only throwing one code p0032 for the o2 sensor on the passenger side I have replaced it with new one but it hasn’t went away. Kinda lost don’t know don’t know what to check.

 

Do you really expect help after choosing that screen name?

Air filter(s).If you have a lot of miles could be clogged cat. What's changed since it ran well and how many miles?

How many miles on your old tired 350?

 

I have swapped the filter out with brand new one it did nothing and it has 120,xxx miles
I did the timing chain and tensioners but it ran perfectly after doing the timing and then just start doing the idling issue.
