P0301 - Cylinder 1 Misfire Detected

The Crankshaft Position (CKP) sensor circuit is monitored by the Powertrain Control Module (PCM). From the data received from the CKP sensor, the test fails if a fluctuation is detected by the PCM when cylinder 1 is to fire.

Possible Causes:
^ Improper spark plug
^ Insufficient compression
^ Incorrect fuel pressure
^ The injector circuit is open or shorted
^ The Injector
^ Intake air leak
^ Lack of fuel
^ The ignition secondary circuit is open or shorted
^ Drive plate
^ Front HO2S
^ Incorrect distributor rotor

Diagnostic Aids:
Perform a cylinder balance test. Number one cylinder should respond.
