This may be due to low fuel level or fuel gelling in cold ambient temperatures. If no root cause is determined after normal Powertrain Control/Emissions Diagnosis (PC/ED) pinpoint test MA, recommend that the customer use a different brand of fuel and use Motorcraft® PM-23-A Diesel Fuel Anti-Gel and Performance Improver.
