Check the temp first then remove freon as needed. I usually know how much to put in

 

Just vacuumed and recharged the system. Current readings are around 225 on high side 45 on low side. Maybe the system was over charged. Temp through vents gets down to just above 40 Fahrenheit when driving. At idle it raises up to around 55 to 60 Fahrenheit. Not sure where to go with it from here. So far the receiver dryer and expansion valve have been replaced. Ambient temp is around 90 degrees today.
Update : I noticed a burning smell after running the ac for a bit after charging. After researching, I associated that with being the condenser going out. I also noticed after further research I used pag 100 oil to put in the system. It is my updated understanding that's too thick of a viscosity, and that I should've used pag 46 instead? So i drained what oil I could from the compressor and replaced with pag 46 oil. Running a vacuum on the system and charging it now and will update on how that turns out when I'm done. It's hotter than a 2 dollar pistol out there right now so I'm hoping to get this figured out once and for all. Current ambient temp is 99 Fahrenheit.
