Incidentally, i also have a blocked EGR valve that I will try to fix or get fixed.
Could some one with excess time have a look at this video. It is for removing and fixing the EGR valve on my car.
Now, what does the EGR actually do to fuel economy. I am not entirely convinced that it has any unburned fuel left in it. It seems to me that it is just a means to stuff an uncombustible gas in there to make the relative engine size smaller.
Now if you look at the video, the guy connects to the ECU and looks at some parameters before and after the EGR fix. What if i were to use my steam injection and completely get rid of the EGR?
I was thinking of tapping in to that solenoid feed and boost the steam injection up when the computer called for EGR.
What do you think of this? Waste of water? Keep engine cleaner? Loose economy?
I could be completely wrong about this so please correct me if my mind has wondered down a wrong path.
