Hi All,

Yesterday I went to start the engine cold, the starter activated normally, but before idling normal, it was like like only one cylinder was firing and the engine did a slow surge between 0-500 rpm for a couple seconds before firing normal. Should I be concerned about injectors? Spark plugs and battery are new. Also it was not cold outside, so this is not the same noise as a slow starter turning a really cold engine. Car ran normal after that and started normal coming back from work.

This happen to anyone else?
