The air suspension adjusting/pumping? I hear it too but it comes from the rear.

I have the same popping sound. It happens at idle about every 20-30 seconds. I have a 2006 EXT. I have installed headers and dual exhaust so I thought it had something with the vehicle running too rich or something? I took it into the dealer last week and they said that the sound was in the "normal" range. I don't know what that means?

If I could put in my two cent I will. It could be your wires that are shorting out on one of your cylinders, thus the gaps between your popping noises. or If you are puting regular unleaded fuel you might be getting pre detination.
Just something to spark ideas in the forum..
