I have the E250, but I'm not clear on what he's looking for?

 

How many cats and how many downstream sensors, Brew. Isn't it just one of each when it's 49 state and over 8500 GVW?

 

I'm not sure, I'd have to look it up on the service DVD. It does say something about that, but I can't recall of hand.

I know some went with just two converters, - had a diagram of it with the different set ups, but my albums were deleted on this site. Starting over.

Oh and they still have 4 sensors from what I recall. Should I look it up ? - 99 E 250.

 

I'm 100% certain it only has 1 downstream and 1 cat. Being that it's a cargo van it doesn't have all the bells and whistles like a luxury van so it's pretty easy to look around for different things. Now yall have me wondering if it has the wrong flash or pcm and this was a temp fix from the previous owner............
