I cleaned my throttle bodies. MAF sensor. What could it be ? It's annoying to drive stick like that. When it's warmed up it still idles there.

 

Probably need an idle relearn after messing with the throttle bodies.

 

I didn't touch the butterfly though

 

Maybe, but what your describing means you need an idle relearn. I did the same thing on my Maxima. I cleaned the throttle body but didn't move the butterfly and my idle was about the same as yours. Idle relearn fixed it.

For the"throttle valve closed positioned learning Procedure". What does it mean by "Make sure that throttle valve moves during above 10 seconds by confirming the operating soundd" ??
