What could cause a high EPR gauge over-reading? (i.e. on all 4)
borescoping?
compressor wash?
p2T icing (a la Air Florida 732 - AF90 on 13 Jan 1982)
CB's tripping/left out? fuse blowing?
bleed-air selection? aircon configuration?
some pneumatic function?
Overnight parking plugs left in?
Are these EPR gauges easy to misread? The N1 gauges?
What could cause a crew to roll, become distracted and forget to get the correct power "set"?
Would sabotage show up before their t/off roll? (vaseline or ???over the Pt2 probes?)
