Not an erratic idle like a dirty throttle body gives you. That goes up and down when the AC compressor kicks on, and can send the idle down to 300-400 RPM and stall the engine out. Then it overshoots when the compressor cycles off.
death rattle. a sound produced by a person immediately preceding death, resulting from the passage of air through the mucus in the throat.
Anonymous said... my father died one month ago today at a hospice, and the death rattle was there for a few hours before he died. the nurses know the rattle is a sign of death so told us to be prepared. although the rattle is not a nice sound at all id say my father passed away very peacefully.
