I have a 98 accord 4cyl w/ 49,000 miles that I have owned for 5 years. This is weird. There is a strange hum or buzz underneath the car. It happends about every 5 minutes or so and lasts about 10 seconds. Everyone thinks I am crazy. Any Help!!???

 

Could be a loose heat shield on the exhaust? It's hard to say without hearing it.

 

sounds like the abs resetting....tough one to diagnose with the info given though

 

Too me it sounds like a electric fuel pump....Maybe?????

By the way I'm sending this to the General Forums..
