Engine noise
#31
Be smarter then they are. Go to radioshak to buy digital audio recorder and then install it in deferent places. Make an recording and figure out where this noise come from.
I do have more complicated noise.
“Mazda3 2008 2.3L (AT)
When I drive a car on quite route at 35-37mph at 5 gear speed and slightly accelerate, RPM drops from 1750rpm to 1500rpm as a result of it I hearing VALVES slightly knocking.
It doesn't happen when you switch manual gear level.
I was in dealership two times and they didn't hear anything or doesn't wont to hear.
What kind of sensors is malfunction?
What do you think?”
Today I got OBDCOM diagnostic tool, digital recorder. I'm going to collect all evidences and then go to dealership.
I think they doesn't want to hear anything under a warranty until you show them what exactly problem is and show them how to fix it.
