OK, I believe you have it right.
I turned engine on and got:
25 psi low side and 125 high side with compr off and when comp kicks on it goes to 22 low side / 130 high side.
It cycles about every 10 seconds and to me that indicates a low charge which now makes sense with the leak I found.
Since the system already has 134a in it do I have to evacuate it after I change the lines, orifice and accum? I have everything except a vacuum pump and was hoping to do the work myself-with tech help of course. I read everything on gnttype.org on these systems.
