Abstract
Methods and systems for operating a glow plug are disclosed. In one example, current supplied to a glow plug can be controlled to promote combustion stability of a cylinder after an engine start. Engine feedgas hydrocarbons may be reduced during conditions where combustion stability may be otherwise reduced in order to reduce tailpipe emissions.
