Rattling Noise While Accelerating

40

Asked by Jan 27, 2017 at 06:53 PM about the 2004 Honda Accord LX

Question type: Maintenance & Repair

I hear a slight metallic rattling noise coming from the front of my car when I accelerate. The sound disappears after reaching 35/40 mph. I don't hear the noise if I take my feet off the gas pedal. A local auto shop told me that it was due to a broken heat shield, but repairing that did not stop the noise. What can be the cause of this problem?

Is the engine pinging? Try a higher octane gas.

Here is a way to help in diagnosing this sort of thing put the car up in the air on a lift or jack stands and having someone "drive" the car with someone listening underneath. You can simulate a load (acceleration) by applying the parking brake for a short time. You should be able to locate the sound that way.

Is the check engine light on? If so it could be a problem with the knock sensor. The knock sensor is supposed to retard ignition timing if it hears the engine pinging or knocking. HTH. -Jim

Thanks everyone for your kind suggestions. The engine is not pinging and the check engine light is not on. Can it be due to problem in the cam shaft belt?
