Default Heat and Idle issue

This is what i have that is the motor

1995 Civic EX (D16Z)

JRSC (9lbs boost)
JRSC Fuel Pump
JRSC Fuel Pressure regulator
AEM Intake (NEW)
MSD 6 With boost retard
MSD wires
Gude Throttle Body
ACT Clutch w/ Flywheel
99 Civic Headers

This is what i have replaced in the past week.

Radiator cap
Timing belt
super charger belt
power steering belt
Honda Metal head gasket
Honda water pump
Cap& rotor
Denso Plugs
Injectors (stock)
Fuel rail (stock)
AEM Intake
Thermostat (170 degrees)
02 Sensor
New oil change
Coolant flush

With all these things replaced I still have a odd idle speed when at a complete stop about 1500 rpm if i hit the gas real qwick it will idle at 900 rpm. still to high i should be 650-750 rpm.

When i get on the freeway and boost it reall qwick it will idle really high when i put it in Nuetral @ 4000 RPM and i have to down shift to get it down from that.
Issue 2
I also have a cooling issue as well.
The issue being it will heat up a past way past 210 Degress then i will have to turn on the heat to disipate it. We did a correct 50/50 mix and let it sit to get air out of the lines. Also hiiked a pressure tester to the coolant system it help like a champ @ 17lbs

Issue 3
Replaced the O2 Sensor and my gauge says that i am runnig all the way lean doesnt even read at all. When i do start from the morning at a cold start it will go up but only half way sometimes more but a mile down the road it drops Big time all the way so it doesn not read.

I have tried 3 O2 sensors and all the same senario and i know the gauge is right because my car runs like poo with no fuel. There have been a couple and i do mean a couple of times it went all rich and pulled like a scared puppy

So i am at a losing point and cannot think of anything can someone help ? Thanks in advance.

Any suggestions would GREATLY appreciated
