Has anyone been having problems with their 4X4 trucks in the snow??? We had almost a foot of snow and at some point my truck started to bog down really bad, the following day i had to go through about a foot of snow and the little wrench light came on and the truck was bogging down at that time. Now yesterday I parked or had to park in some snow so I pulled in and only my front passenger side tire went through snow and now my check engine light is on anyone have any ideas on what triggered that engine light????
