Sooo confused!

This is like Explorer Twitter!

I know that on one of my old trucks if I changed that vacuum tree of red, green, and white tubes, my light would go out. Same with the EGR solenoid that you're changing. But I never had a blinking CEL...

Well there is only 3 components in your EGR circuit. The EGR, the Solenoid that controls it and the Sensor.

You replaced the sensor and cleaned the EGR as well as your mechanic performed a static vacuum test. I would change the solenoid out (about $30.00 part) and replace the vac line from the solenoid to the EGR. Also check the vacuum line going into the solenoid. it is rigid and may have a crack.

I assume your mecanich also checked your EGR for a leaky diaphragm.

That vac line is the one I was speaking of- be VERY careful removing any component of it, it cracks VERY easily since it has gone through so many heat/cold cycles in the engine bay...
