its been cold up here in Canada and I fired the ol girl up at about -10 weather and it ran kinda rough an the check engine light came on so I plug the machine in an it read Random Misfire Detected so I didn't erase it I have the truck booked in at for for other thing so I though I would leave it till then then comin home from town and never notice I looked down and the light went out and hasn't come back on since.

still runs good

Can somebody explain what the h*** just happened lol

 

If i am wrong someone correct me lol. My truck had a misfire also and had to replace the spark plug,anyways while i was doing that i had to take out the coil pack to get to the spark plug and saw that the coil pack had a conector maybe one of your connectors got frozen,humidity in it or something and when that got out of it, caused it to go back to its original state i dont know if that made any sense but it is just a thought lol

 

you know that theory could be it it's been weird weather up here cold ground freeze then sun comes out and made everything mud for a week then froze again, and I put a lot of miles in the mud so something could have got in there
