GTcarz - Automotive forums for cars & trucks. - 97 accord, strange "ernnntt" sound

Try and determine if this sound relates to rpm - rev the engine slowly in
neutral. My guess is that it does. I used to have the same problem with my
Prelude and it turned out to be the baffles inside the exhaust system. A
slap with a rubber mallet cured it. However, when I got my 96 Accord, I
noticed the same problem but it was something completely different. It was
internal but closer to the engine. The Honda dealership stated it was
covered under warranty - for the life of the car as I had it repaired in
2002 for free by Honda. The problem then came back 2 years later but this
time it turned out to be the heat shield. The only way I figured it out was
to get under the car while running and someone operating the gas. Try this
course first.
