I asked Alex Peper what would be the most useful/helpful book should I first start with when I get my Tricom?
Told me to check out the library for Mitchell's. Good source for troubleshooting.
I can't confirm yet, Mitchell's at my library having mainframe problems.
Be nice to have a copy that the Ford mechanics use, but two problems I'm assuming. 1. Not availble to public/propietary? 2. Might only make sense if you have their laptop/Star System or whatever it's called?

As with any troubleshooting tool learning how to interrupt always fun.
Oh yeah, higher EGR flow, downstream restriction is only logical reason thing I could think of at this time.
