I think i may have posted this in another thread, but I i tested the EGR control valve and with 12 volts it does provide vacuum, also with a vacuum pump to the EGR and car idling it will run rough like it should.
Putting it all together and have driven it about 100 miles for testing cruise and other stuff on the car and going to work for a week, and the egr still doesn't appear to be working, nor getting a check engine light, and I got between 45-50mpg on my 100 mile fill-up.
I guess i'm just going to not worry about it for now. Oh, i also substituted another federal VX ecu, and nothing changed. I've got a 3rd federal one I might try, but i suspct no changes with that as well.
