idle?

[icer]

What rpm's should my 91 240 be idleing at. Right now its like at 1000-1100, but someone told me it should be around 750-800?

it will be above 1K when you turn it on, and it should drop to 700-800 when it is warm

Also depends on alot of other little things.
getting a tune up will change the idle. (in a good way)
Once you've done alot of mods that will also affect your idle which may or may not be in a good way.  Some will raise the idle and some may lower it.  Some mods will increase hp but not make your car idle as smoothly, especially with the factory ecu.  Its just not programed to handle those kinds of things.
I wouldn't worry too much about where it idles.  I'm not saying to ignore it, just that the idle changes based upon alot of conditions (temp of the air, engine temp, and mods to the car).

uhh isnt it also true that ur idle doesnt go thru ur throttle body cuz thats completely closed when ur foots not on the gas, so it bypasses that and goes thru a secondary air inlet? wouldnt the size of that affect ur idle rpm too...?
