If its been a while sense you have chg. fuel filter,DO IT, If still does the same after that, do fuel pressure test, fuel pump might be on its way out. $$$$$. If pump and filter chks. out ok, than maybe its fuel regulator. My best guess its either filter or pump.

Check the fuel pressure, bad fuel pump or sock on the fuel pump and fuel filter check spark plugs and check distributor cap, a fuel pump is $273.00 or a bad injector $110.99 or BWD Fuel Vapor Pressure Sensor for $35.99 any of these parts could cause the problem, so without doing a fuel pressure test it is a guess, if the vapor switch is bad it could cause a long crank time if the fuel pump is bad it has a check valve in the fuel pump, if the check valve goes bad the pump can't maintain fuel pressure so on start up the fuel has to pump from the tank all the way up to the fuel rail, if the injectors is bad it could leak after engine shut down and cause you to lose fuel rail pressure. Also the fuel vapor sensor could be stuck open and could cause the problem, all need to be tested, you can rent the fuel pressure tester from AutoZone or advance auto or Shucks they return your money when you bring the tool back as long as you buy the parts to repair it from them. That would be the first thing I would check fuel pump pressure and if you replace the pump then change the fuel sock as well. That model was not meant to burn ethanol and can kill the fuel sock the fuel pump and filter.

CHECK AIR FILTER FOR RESTRICTION. A BAD SUPPLY PUMP. OUT OF FUEL. BLOCKED FUEL RETURN LINE. AIR LEAK IN SUCTION LINE. RESTRICTED FUEL FILTER. INOPERATIVE FAST IDLE. LOW IDLE SPEED AND DEFECTIVE INJECTION PUMP.THIS IS A LIST OF THINGS TO CHECK.

take out your mass airflow sensor located on air intake pipe and clean with brake cleaner also is your engine light on?
