I can blow in air into the bottom port of my 94 EGR modulator. The big hose to the bottom of modulator is not a vacuum but a pressure hose. On my fj60 modulator I can't blow air through the bottom port. The bottom port on the 60 has a diaphragm that opens and closes when I blow in it. Is the 80 modulator the same setup.
Could this be my problem?
