Hi all.
Hope someone can point me in the right direction,
When the temperature is above 18'C and starting from 'cold' my 2012 Altitude idles very rough
for about 20 seconds then clears and runs perfect. When the temperature is below 18 there is no problem. It sounds like there is a sensor that has gone out of its range. Any ideas ?
