My Liberty is Farting

I don't know how else to describe it. 2002 Liberty makes a noise on occassion that can best be described as it sounds like farting. Fortunately, there is no stink that accompanies it. Happens maybe every 20 minutes or so. I have no clue as to what this could be. Any ideas or similar sounds coming from your vehicle?

You have to stop mixing refried beans in with the gasoline! :shock:

Is it happening when you're driving, when you're idling, or both? Does it happen at all speeds when driving? God forbid it's doing it when the engine's not running!

Does it happen when the jeep is sitting and not running?

If so, its the evap pump kicking on to check the system for leaks.

Also, do you have an aftermarket exhaust?

1st couple of pages were the jokes - but this seemed like a possible cause

I do not have an aftermarket exhaust.

Typically happens after about 20 minutes of driving and just as I am letting up on the gas. I believe it happens at all speeds but difficult to hear at highway speeds.

Occurs with AC/Heat either on or off.

I can't remember if I read about it in the Factory Service manual or on another thread. But I beleive it said this can happen to the evac system on the fuel tank. I thinks that the first possible problem of KJ flatution. :oops:
