My name is John, I am new here. I drive a 2020 3500 Ram pickup. It is equipped with cold weather block heater. The temperature over night was only in the low 40s but I had it plugged in. I started it this morning and the temperature was already warm so I drove off having idled for only a few minutes. It drove like there was very little communication between the gas peddle and the throttle. it did this for about five minutes then everything started working properly. Has anyone experienced something like this? Is this a precursor to something worse?
