Do you think this is a blockage some were like in the txv. The only thing i am not 100% confident about is the evaporator. I didnt take it out of dash to clean it; all i did was blow 150 psi air through it. I Put more oil down the evaporator and blew it out with air again.

As the refrigerant leaks out, the evap temp will get lower as the suction pressure drops, and the clutch will cycle more frequently as it cuts out when the suction gets too low.
Common symptoms of low refrigerant charge, along with the evaporator icing up. After all it is getting colder.
