S500 partially stalling and no power
Hello
i bought my S500 2006
2 days ago
the problem is
while i drive the car sometimes dose not response and cuts power from the engine as if your pressing the pedel but the car is stalled
not smooth acceleration it cuts and goes rough and some times
stalls and even if i press the pedal there s is no power the speed is constant
there is no check engine light on
i changed the Fuel Pump - assuming there is no enough petrol going to the engine still no solve
changed fuel filter - still no solve
changed the spark plugs - still no solve
changed engine oil and filter - no solve
--
i bought OBD 2 and scanned for fault codes
All faults came as power train
OBD-II DTC: P0171 System Too Lean (Bank 1)
OBD-II DTC: P0175 System Too Lean (Bank 2)
-
list of fault codes -
please any thoughts ?

Something seems to be going on with your electrical system. Maybe check for simple stuff like loose/corroded wires, maybe something got unplugged, battery voltage, alternator, blown fuses/relays. The electrical systems are so complex without star you might have to take it to somewhere that can diagnose where the problem is coning from
