Popping noise from somewhere in engine area

I recently started getting another difficult-to-explain, only-in-a-jeep type of noise. After I start slowing down or just slowly coasting, i hear a CLANK! similar to a popping noise, or as if I was driving over a loose manhole cover, very similar to that. SO many times I just looked behind my mirror to see if I actually did.. Well sometimes the noise comes up when I am stationary like at a light or jam. Sometimes it comes from the left side, sometimes near the center.

Jeep runs fine otherwise. Any ideas what this could be? No A/C during the noise.

No error codes when you turn the key for the first time? Do you know how to check for error codes?

Are you talking about the spline klunking noise when coming to a stop?

I only have P441. But I've had that for almost 1 year. Bad purge solenoid.

jakewire, not sure that I know what spline clunking noise means. The noise is not associated to a acceleration, braking or bumps. It is completely random. Almost like a cap on top of a metal pipe, it is lose and then it finds its place and settles.. Clanky..Blap!

Do you have to hit the brakes for it to do it or does it do it if your just coasting and slowing down?

Haha, he knows what the slack in the splines is like so its probably not that. Hes talked about that before.

No, not that dreadful slack in the drivetrain.

Blake, this is completely new noise. It could happen when I am driving 20mph on a flat street, or when I am pulling over to park. As soon as I hear it, I turn the radio down and wait for it to come back.. It doesn't --only to happen when I forget about it and stop listening for it. And than cluck! it is there..

Not sure if you have lose manhole covers where you live, but it is common here in NY. This sounds just like as if I was running over one.

I know our GMC at work does something simmiular & the noise is coming from the gas tank & it's random

kinda like it's getting sucked in then pops back out

Mine is from the front.. Well, let's see if it returns, or becomes more frequent.
