After a while of driving sometimes at idle I will hear a small popping noise. It is pretty noticeable and I can't figure out what it is. At a low idle (700rpm) my oil pressure is around 24#.

I also have a wideband installed and my car is close to 14.7, a:f so I don't think it is that. My throttlebody also started whistling too this week.

Any ideas?

My car does something like what you described also and it's a carbed engine....it almost sounds like a miss....or like a really really mellow backfire. Most 5.0s i've driven do it though so i never worried about it.
