gpollock87 Posted March 7, 2015 Report Share Posted March 7, 2015 I started my Deville up yesterday and it started to miss when idling and when I stop and take off it shakes. I drove it home Wednesday with no problems and this started yesterday when I started it up. The check engine light is not on. I thought I might have gotten bad gas Wednesday. I put Lucas fuel treatment in it yesterday and it has not helped so far Quote Link to comment Share on other sites More sharing options...
