I need a little advice on something.
My D90 is making a popping sound.
It sounds to me like a backfire but I am not sure.
It happens in the first 3 gears, when I take it over 3000rpm and then back off when it is coming down I hear the odd popping sound. I have dual exhausts, and it certainly has a nice burble to it but I can't tell if there is something wrong, or if it is just what these V8's do.
I am used to the Diesels.
If it is the start of a backfire, what is the problem and do I need to fix it now before things get bad?
