After doing the rear valve cover gasket, upper intake gaskets, and the throttle body gasket replacement, I am getting an occasional odd idle condition.

When coming to a stop, the car doesn't want to idle back down to normal. Instead, it wants to stay around 1700-2100 rpms. If I turn off the car and immediately restart, the idle goes back to normal. This doesn't occur at every stop. Random really.

 

what kind of gaskets did you use? Sounds like a small leak.

 

Gasket set was Fel-Pro.

 

Wonder if replacing the TB gasket somehow messed with the idle and an a re-learn procedure is needed? I had a tough time getting the idle to come back down to spec after a TB cleaning. Ended up doing the fuel injector unplug trick during the re-learn.

 

My other readings indicate possible Idle Air Control Valve (IACV) is failing or needs cleaned. I found some videos on that.

What's the re-learn procedure look like for a 2001 Maxima?

 

I think you can delete my comment. I don't think the drive by wire throttle body started until the 5.5 gen (2002-2003).

 

I found this for the Idle Relearn Procedure for a 2001 Maxima. https://www.nissanhelp.com/diy/maxim...e_learning.php

Will try it out.
