This is my first time on this message board and I was wondering if anyone could help me out. I have a 95 Honda Accord LX V6 and there is a dull drawn out sound coming from the engine. It sounds like a low humming sound. The noise is sort of similar to a car with an after market exhaust but this sound is comeing from my engine. The sound only happens when i accerelate. I took it to a mechanic and he said that it is just the overdrive and that I shouldn't worry about it. I have never heard this sound from my car before. The sound is really prevalent when I am driving between 60-70mph. I haven't lost any power and I don't notice any driving difference, just the noise. My car is 7yrs old and it has 121,000 miles on it. Maybe this is just natural for a car this old, I'm not sure. Again, any help would be appreciated.
