95 s500 surging help

95 s500 while driving feels like you just turn the key on and off in 5-6 sec ond intervals. then it will just run fine for 5-6 miles. but today it just kept
the on and off acceleration pattern so i limped home. Idles fine, please help!!!

first check condition of engine wiring harness.If its fine check condition of plugs,and wires.Clean Mass Airflow Sensor.
After that and no fix let a Auto parts scan the car.It might to be throtle posistion sensor,also as simple as fuel pumps.
