What is with the cat. converter replacement. Did anyone buy the universal converters and try using them instead of having the dealership put them on? I have the codes for both converters below efficenicy for the Duratech V6.
Thanks for the advice. The pre-cats on this are a horrible design. Ford wants $900 just for one exhaust manifold/pre-cat.
While there is a good chance that your Precats are shot, I would change out the Bank 1 Upper O2 sensor and check/change the DPFE sensor first. Then reset PCM and see what codes come back before messing with the precats.

You are correct. TBcleaning does help clear EGR passages.Tony, before he does the DPFE, I think it would be a great idea to perform the Throttle Body (TB) cleaning to get the gunk out of the EGR passages. It is possible he may not need the DPFE at all.
