Re: Sputtering, idling shakes the car
I'm thinking that your fuel system is iced up. Try a couple bottles of gas line antifreeze. Also, it wouldn't hurt to run a bottle of fuel injector cleaner in the gas. It's possible the plugs could be iced up. Will it run long enough to heat the engine up? If it will I would rule out iced up plugs. When it's really cold the condensation will freeze up your plugs if it doesn't go ahead and run on the first try.
