I can think of many, many things that might cause power to be reduced... I would not go chasing after diagnoses based on a post on the internet...

First course of business is to run a diagnostic scan from the DME- see if there are any codes, This forms the basis for a first pass guess. You integrate the reports from the DME with complaints/driveability... come up with 'what part must be bad to cause this code and this symptom'

Without a scanner to look for codes, you are pretty much sol.
