Jasper350

hey, so i've got a problem with my 2003 Nissan 350z. When i try to start my car for the 1st time of the day it takes like 2-3 minutes of cranking the engine before it starts. after it started the 1st time and i try to start it again in a few hours it just starts right away. and while driving it you don't notice anything wrong. i do get a engine code P0021 but no check engine light. help would be much appreciated.

My guess would be the camshaft sensors

I had the same issue with my 2015 Sonata 2.0T. Ran a P0021 Bank 2. It's a quick fix (was literally 30min for me at the dealer) but do it asap because eventually you wont be able to push it past 2-3k rpm. I don't recall the specifics to it but iirc it had something to do with my OCV.

Also not trying to be a dick but a simple search would have saved you time of posting in here. There are multiple possibilities when you run that code.
