I need to know how to adjust the idle on my 1990 honda accord ( i know it can't be that
hard, but i'v never done it before). My car idles at around 400RMP and then jumps to about 700Rpm when it get's to low. any links to a diagram would be great.
Thank you.

 

If i take it somewhere they shouldn't really charge much to do it....right?

 

They won't charge much just to change the idle but they'll damn sure find a bunch of other stuff that they can charge you for.

I'm not an expert on '90 Accords, but there should be a screw on the throttle body that you can turn to adjust the idle...

Yes there is. It's right above the intake tube and it's covered in protective rubber. (a flat head screw recessed a bit into the t/b) Once you find it give it a slight turn till it's at about 700rpm.
Keep in mind the next line just above 0 on your tach is 500 rpm
