Default my 2001 honda crv is making a pup pup noise from the exhaust?

i was told this could be because of the spark plugs being old and not working right.so i changed then along with the leads .one of the plugs was completely dun in so i thought i had fixed the problem,but the exhaust is still making the same noise .could this be a problem with the injectors?any help would be most appreciated.

I wonder what you mean by "one of the plugs was completely dun in"? Was it mechanically broken such that debris could have fallen into & damaged the cylinder? You need to do a compression test. If it passes the compression test, then yes it could be a bad injector. If it fails, then you could have a stuck valve or blown gasket or some internal damage.
