hey guys i'm just wondering what the normal idle rpm should be. i've got a 92si with the d16z6. when i come to a stop sometimes the idle will drop to around 100 rpm and the car vibrates but never stalls out. is this normal? what do you guys idle at?

 

I idle at 800 +- 50. Yours should be about the same.

 

That bottom line on your tach is 500, not 100. So you're probably idling about 600 or so. That's happened to me in my old car, and I've heard it's fairly common. Not sure what the cause is, but I know it's not like, life-threatening.

 

haha my bad i guess around 500 then. i've read stuff about the iac getting clogged? could this be a possibility? i know that if i just slightly hold the throttle it smooths out. is there a screw somewhere that i can use to adjust the idle?
