I have a 1992 gt4 with 115k on it. I recently took an emissions test and passed on everything but my NOx
were too high. I was wondering, if someone here knows how this egr system works? The valve does hold a vacuum
but the control valve is allowing a vacuum when not being supplied power and closing when it gets power
Just didn't know if that's how it is supposed to be.
I tried searching with no results.
Any help will be appreciated.
