I just want the problem fixed, mostly. I do like to see how things work, but not when it's a pain to get to. And yes, Ron (lol), a hammer would get me to it, but may destroy the evidence at the same time.

Having said, I want to update that after having cleared the CEL by disconnecting the battery, it has not come back on after 3 days of driving. I still haven't gotten it on the highway at over 60 for longer than a few seconds, but I will.

So, hopefully changing the DPFE did the trick.

Thanks Ron and Jeff for the feedback. I'll only revive this thread if the same code pops up again.
