I have a '95 Lesabre that when it is cold it will not run correctly. I can crank it and it runs perfectly in park and when I put it in drive it starts sputtering but will not rev up or go. I can put it back into park and it still does the same thing. I can turn it off and recrank it and as long as it is in park runs perfectly as above but put it in drive it will not go. I can let it run in park after a recrank until it has warmed and it runs ok from then on. Could someone direct me to the cause?
