Garrett

This one doesnt have any vacuun lines, it just has one wire running to it. I took it out and cleaned all the carbon out of it, and I cant see if its working or not.

this is a 1993 subaru loyale with an ea 82 engine automatic. does anybody know how to test the EGR or the EGR coil? i pulled the hose off the top and plugged it and looked down the hole while reving the engine and the shaft didn't move. Does this mean its not working or is there another test?
