Last week my '03 318i started to hesitate while accelerating, but after the RPM's got higher, it would go like normal. This behavior continued until eventually the hesitating was constant and the engine light came on and started flashing, so I parked the car to prevent getting stranded or damaging the engine. I got an OBD2 scanner and it brought up 3 codes: P1343 (Misfire Cylinder 1 with fuel cut-off), P0327 (Knock Sensor 1 Circuit Low Input bank 1), and P1327 (Knock Sensor 2 Bank 1 Low Input).
I replaced the Spark Plugs, got the injectors cleaned, and the fuel pump is a Bosch unit that was replaced 3000 miles ago. I originally thought it might be the fuel filter, but now I'm second guessing myself. If it was the fuel filter, would there not be a problem with more than one cylinder? Any help would be greatly appreciated!
