High Idle after valve cover replacement

[abnrjd]

Replaced the valve covers on a 2004 Nissan Pathfinder and cleaned the throttle body as well as the upper and lower plenum assemblies. It idles high, around 1100 rpms, can the idle speed be adjusted?

Is your CEL on? I ask because if it was, then you probably jarred a hose loose and have an intake leak. If not, you can try doing the idle relearn process.

I believe any time the throttle body is cleaned, you need to do the idle relearn. You can run a search on here on how to do it, or you look in the factory service manual.
