Still having dash out and no electronic throttle issue with this 312. Ive checked grounds relays and fuses with no luck. I noticed ecm has a red and green light lit which fades on and off without touching anything which makes me suspicious of a bad ecm. Its lit solid green when running with no issues. Its been doing this intermittently for a while. Also when I bang on ecm lights flicker. I jiggled wires going into ecm and no change.Does any one have a service manual for this machine or serial is7dkoo640. any thoughts would be appreciated.a wiring schematic would be helpful also if anyone has.
