What causes popping sound in exhaust at idle?

Now if the car sounds like a real slight miss or pop at idle, it could be a burnt exhaust valve or an exhaust valve not fully seating and seal properly. It could be spotted in a compression or leak down test. It probably won't cause to much of a problem for now, but could cause some damage down the road.

Also asked, what causes popping sound in exhaust?

The "burbles" or "popping sounds from the exhaust" as you have crassly put, are a result of exhaust back fires. In some cars like the "RS" versions of Audi, there are Ace injectors that especially inject fuel into the exhaust to make those "pops and bangs" during deceleration, Downshifts or as programmed to.

Additionally, what causes engine popping? If your engine is getting more fuel than it needs, a rich fuel to air ratio is the result. When your car has leftover fuel in the exhaust and the cylinders, that fuel explosively burns and creates a loud popping sound. Specifically, here we mean delayed timing, which causes the backfire.

Also know, how do I stop my motorcycle exhaust from popping?

There are many ways to stop the bike from backfiring and some of them are as listed below.

  1. 1) Keep a Check on the Carburetor. The engine will run clean if the fuel cannot flow properly and the main cause for this is a dirty carburetor.
  2. 2) Fuel Injector Cleaner.
  3. 3) Keep a Check on your Jets.
  4. 4) Change Fuel Grade.

When I accelerate I hear a popping noise?

If the popping sound is more rhythmic and occurs more frequently as you rev the engine, you may want to look for an exhaust leak. A blown exhaust gasket can cause some pretty loud sounds from that area, but it will always be louder and faster as you rev the engine higher.
