Info needed about EGT sensors, on my RWS EM2 #2 EGT about every 10 seconds will come up as 4000 deg. F. or so.  Is the sensor going open or shorted intermittently.  Have not checked it yet, just removed break-in oil after 24 hrs. run time & went with 20w50w full synthetic, getting ready for first flight ( got delayed last year by coolant & oil temp readings in-op., solved & my youngest daughter grad. EMU, Meagan & Cody moved to Bloomington Illinois for Cody's new job, with dad as one of the movers ).    David R. Cook  RV6A Rotary  Lansing MI.
