Just have to ask, are you sure the vacuum lines to the EGR are not switched? For code 52: Knock Sensor Circuit (open or short in circuit) will never go away if you bypass the knock sensor. I understand tho that is a popular thing to do on older Toyotas according to some of the forums I visit.

Yes I'm sure they're not switched. And the hose is suckling to hard for being at idle. And the symptoms of a knock sensor are still there as far as lag in the motor.
