93 Del Sol SI
has a little over 181k miles
runs great, other than.... my idle issue.

Have replaced:
IAC
Throttle position sensor
ENTIRE distributor
Plugs & Wires
PCV and hose
Timing belt & Water pump
It had a vacuum leak, but that is fixed and smoke tested and there's no more vacuum leaks
Valve cover gasket
Coolant was burped after all that.

ANYWAYS, so the issue is that it idles at 700 and that's with me running fans on 2 constantly. If I turn the fan off it will idle at 500 and rough as hell.
Sometimes when I first start it, and it's not warmed up, it will idle high (like any normal car) then it will drop, then go back up like nothing happened. But once the car warms up is when the constant idle issue occurs. So basically I just drive around with my heat on (since it is getting cold) and it's fine, but it needs fixed. Any thoughts would be greatly appreciated, and I hope this all makes sense, sometimes I'm not the best with explaining everything haha.
