When I start my car it will run for a while then just die and it will do the same when I come to a stop or slow down at lights to park and so on. Also when I am driving at a high speed it jerks like it wants to die when my foot is not on the accelarator. When I am idling if I keep my foot on the gas it will stay running. What is the problem?
