Here is another victim of this problem. I just did the isolator bolts and gaskets a few days ago and now it idles great. I was really worried about getting into. I've worked on heavy equipment, generators, and airplanes but for some reason tearing into my own vehicle like this made me anxious. But it wasn't that hard and the parts cost less than $100.
However, afterward the light came (grrrrrrr), I checked the code and it was a 1401, some problem with the DPFE sensor. I just replaced this a few months ago. I rechecked all my connections and can't find anything missing. It is running great and was going to drive it awhile and try to clear it again.
Has anyone else had this same code after doing this TSB?
