So I cleaned the EGR chamber today, you know I was surprised, a lot of guides I read made it sound like it was extremely hard and complicated, when it's really not. If you just use common sense, you can't really mess up anything. The CEL is gone, along with all the TC's. No more 'herky jerky' but L/B is still extremely hard to get to engage. Was cruising at 55mph at 37% engine load, running around 65mpg and it just wouldn't engage no matter what I did. Oh well. I'm happy with it, I can apply about 25-50% less throttle at take-off and get the same acceleration.

I would have done a little better cleaning the holes but, my back started going out near the end and I was in extreme pain lol.
