a 00 ranger has a 2.5, the code is a lean code, you probably have a vacuum leak somewhere. get a can of carb clean and spray the throttle body to intake gasket, the iac to throttle body gasket, the intake to head gasket and check everywhere for a vacuum leak. when you spray the carb clean, the engine speed will change when you find the leak
