Jolting/Misfire? when snowing.

[burchster]

I have a 2000 XLT with the OHV 4.0. Everytime in snows there is a jolting that feels like a misfire. No check engine lights just an occasional jolt that ranges from soft to really hard. This only happens when there is snow falling. I can drive through snow already on the ground and even on wet slushy roads fine but if there is any snow is falling it happens. Ive had it in a shop and they scanned everything and couldnt find anything. The only thing I can find is my air cleaner box is warped on one side maybe allwoing moisture in but I really need to find a solution for this because its almost impossible to drive it when it snows. I really like my explorer and dont want to get rid of it but I need something that will make it in bad weather. Has anyone else experienced this with a 2nd Gen?

Use duct tape on the air box or get a new one. Snow goes into the intake and hits the MAF sensor causing the missing...As these vehicles age the bottom of the air box bows out causing air to bypass the filter. This can be fixed with a small piece of threaded rod that you can use to draw the sides in closer to make a good seal. Also, cheap air filters may not seal well as they often have a small rim area. Duct tape will get you up and running anyway...
