I started the car up today and went to shut it off and it tryed to stay running for a few seconds i have never had this problem before and the car was cold i haved had time to see if it did it when it was warm i had some problems with loose plug wires on the plug last week and making it miss and having the manifolds glow would this have anything to do with it
