I have a 2013 Honda CR-V. After I've been driving for awhile, this noise starts--sounds something like when ping-pong balls are being "scrambled" for a Bingo game--kind of a popping/gurgling noise.
It's not part of the engine noise I'm pretty sure. It goes when I have my foot
on the gas, and starts to fade somewhat when I take my foot off the gas. But,
as I said earlier, it doesn't start until I've been driving awhile-- at least 15 to 20
minutes. Any ideas? It's very annoying and I wud like to get rid of it! Thank u.
