Id have to hear it, but if its cracken noise id get off the throttle cause it might be detonating.

Could be a crack in the manifold. I had this noise on my Xterra. It was a hairline crack right next to the manifold flange. Check it out.

I have it on my honda.....i used to have the exact same noise on a toyota and when i looked it was the distributor sitting halfway off.......got a new bolt and it went away...

same noise but the distributor is sitting fine on my honda.

crackling as in bb's in a tincan sound = detonation. Do something about your engine managment fast.
