5.8 EGR
Did a code check and got the 33 for EGR. Depending on which book you look at it could be not opening or not closing. Anyway I replaced it which was a pain because the tube broke too but got it done with a new sensor and still get the 33 code. New valve so it should be closing properly. No vacuum ever to the EGR as far as I can tell. When I rev it up it should get vacuum right? Vacuum solenoid? Or computer not sending the right signal? How do I know which? No vacuum leaks and vacuum gets to the solenoid but never past it.

I checked vacuum line with a vacuum pump and it's good. I read somewhere here that solenoids with grey caps are not interchangeable with black caps. Mine is grey and O'reilly only has black. I wonder if that's still true?
