engine idle speed?

[WhiteNissanS13]

my 240sx(dohc) has 155k miles on it. when im driving it around, when i press in the clutch the engine drops down to about 450rpm,and all the lights dim. <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/huh.gif" border="0" valign="absmiddle" alt=':huh:'> sometimes it drops down to 450rpm and dies. <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/cry.gif" border="0" valign="absmiddle" alt=':cry:'> Does anyone else have this problem?

also, i have a major grease problem on the door latches(the hook that the door latches onto), i always find the grease to end up on the side of my pants. does anyone know a good remedy to remove all or some of the grease?

In order to remedy the grease problem, wipe it off =) &nbsp;Easy as that.

The idle problem is pretty easy to fix. &nbsp;If your idle is low all the time, you can just adjust your idle speeed adjusting screw. &nbsp;It's under the intake manifold (under meaning towards the bottom of the engine from the intake manifold). &nbsp;It's a round adjustment screw. &nbsp;If you are looking from the right side of your car at the right side of your engine, look below the intake manifold, and behind the oil filter a little ways. &nbsp;You should idle around 650 plus or minus 50 rpm (although I prefer 750).

What does your car idle at when it's just sitting in neutral?
