I believe model 933 is the same as 561, with additional circuitry for the EGR. Your 561 probably isn't controlling the EGR since it was intended for cars without EGR. I wouldn't know if that is a bad thing or not (i.e. putting a 561 in your EGR car).

In any case this is how one of my 561's failed. It ran the car OK, but at about 10 mpg... but in my case there were no trouble codes. My dad had one fail where gas milage was only slightly bad, performance was slightly slow, and the car wouldn't idle when cold. Other failures I read about on the board result in not being able to start the car. I have even heard of a couple cases where the car dies while driving. I think the lesson here is that they can fail in a variety of ways.

I enjoyed reading your post.
