1998 Wrangler TJ. Will crank and idle fine. When you reach desired operating speed and try to maintain that speed it will start running eratically and backfire every now and then. Replaced distributor cap and rotor button. Added Seafoam to fuel tank, checked breather. Power when trying to maintain desired speed surges and acts like above description.
