Plugged fuel filter (likely if you got dirty fuel), bad fuel pump relay, bad fuel pump, or most likely, leaking air somewhere in the injection system (KE-Jet? -- if so, boot between air flow horn and throttle body, idle control valve hoses, injector seals. LH-Jet, getting air in between the mass flow meter and the intake valve, not familar with it so can't give specifics).
