90 Ka24e Smog failed stock car

[Trixzim]

Hello,

I went to get my 1990 240sx ka24e smogged today and I failed. Does anyone have an Idea what is causing this?

Failed with this info:
Idle speed CO was 6.13% (Greater that 1.20%)
Idle speed HC Was 683 (Greater than 220 Parts per million)

Do you think my coolant temperature sensor is bad? (Replaced 10/12/22didn't help with OEM sensor)
Or do u think it has to do with thermostat, water pump, and fuel pressure regulator?

This is a picture of my stock engine bay:


Few Things I noticed with my Car:
-Plugs are wet and seemed to be cover in gas. Running rich (You can smell it)

Old plugs

-When I tap the gas and let go, the idle drops and kind of bogs
-The engine seems to be running hot but the gauge is showing about a quarter

Things I replaced:
Engine temp sensor
O2 Sensor (NTK 02 sensor)
New OEM Dizzy and rotor
New spark plugs and wires ( NGK wires and NGK Iridium plugs )
New Air filter
New fuel filter
Timing was check and its a 15 B.T.D.C




Thanks,
