While idling my bounces from 1k to 1.5k rpms.
I have a CEL for code 14 which is electric idle control malfunction,
I have:
replaced IACV
replaced intake manifold gasket
cleaned the throttle body
cleaned all of the intake
bled the coolant
checked for leaks

When you first turn the car on it idles high to get warm, then once warm it starts to bounce.
I tried disconnecting the IACV connector and it only made the rpms bounce faster. I also tried blocking off the air holes leading into/out of IACV and it made no difference. I couldn't find where coolant goes into the IACV though so there may not be coolant going to it.
I also noticed that the radiator fans do not come on once the car is warm.
Could this be the thermostat? I'm stumped, idk what to try next. Any help will be appreciated.

 

Just replaced thermostat...did nothing

 

If it has a fitv u may have to tighten it

 

It doesn't have one

 

Could be a bum ecu

 

well if that's the case, I have a d16y8 head that im gonna put on it once i get all the parts for it so I guess im just gonna have to live with it until then...so annoying though
