Need Diagnostic Help

Shut the car off, Unplug the drivers side throttle body and plug it back in and then crank it back up and see if it goes away. If it does, your throttle bodies have an issue and will need to be replaced. Both of them.

And that worked, drove just fine after! Also, why did that work? Trying to learn how this self checks and resets.

My car did the exact same thing several years ago. There is an issue with one of the throttle bodies. I just put two brand new ones on it. It would happen on hot days.

Where did you get the replacements? Did you get an aftermarket, reman, or OEM?

Brand new Nissan. Don't mess around with aftermarket junk for these. It will have more issues than you want. They were $1200 back in 2019. They may be more now. They may offer Nissan rebuilt.

I had this exact same issue on my Z. I cleaned both throttle bodies and the issue went away. After I cleaned my throttle bodies I did the 3 resets.

First I had a P0101B. Nissan says to do a PCM recalibration. This fixed the problem for about a year to a year and a half.
