It's the evap core. DAHM. So besides the obvious, evap core and heater core swap, what else would you change since you're in there? I was thinking the blower motor. I don't know how strong they are supposed to be, I mean it blows air, but no where near the volume of my wife's new car. Malibu for ref...

Erik! In Detroit huh! Cool. Thank you for decoding the Denso numbers. I do appreciate that! I put 225psi into the system with a cylinder and closed the main valve, left the adjustment valve open to monitor leak down. Sprayed soapy water everywhere for about 35 min checking and watching.

Which makes me lean on evap.
Is there anyway to test the evap while it's in the car?
