2.8s tend to do this.....sort of a pop popata pop as you let off the gas between gears. It does not seem to hurt anything, and may be a combination of incomplete burning of fuel and timing and perhaps temperature. Injector cleaner added to the fuel may help.

edit: trying to remember what a water balloon popping sounded like....maybe you have broken a motor mount.

I have had issues in the past it would back fire and then quit.... if you pump the gas pedal in neutral/park will it pop? If it does I would replace the ignition control module inside the distributor. when its starting to go bad it can cause backfiring and then straighten up and all seems fine. goodluck
