Recently i did alot of regular maintenance to my 94 with 120k on it and now it seems to idle around 500. I think this is the low end of the range (500-1000). It is smooth, but I was curious if it would be better to make it slightly higher, say 750 or so?

 

Well I don't know but mine idles at 750 or 700 i think, I wonder what happened to make it idle at 500 that seems alittle low to me.

 

so to raise the idle speed do i just have to adjust the throttle body set screw or is there a more detailed way to adjust the idle speed?

Typically, on a warm engine, you would unplug the idle air control valve and adjust the air bypass screw on the throttle body to obtain the base idle speed. The Ecu will set a code that you would have to clear, usually by pulling the backup or hazzard fuse for about ten seconds.
