Default Rough Idle, No Power, Shift Trouble

After 3 days of snow I noticed the truck had a little trouble shifting gears at speed and at idle. A few days after that it started misfiring while driving. Then the truck started to idle very rough.

What could this be?

I pulled these codes:


I'm hoping there is something that can be easily fixed that would cause all this.

I wonder if the pcm is going bad with that much going on have you let it run a while to thaw it out and maybe undue the battery for 20 mins to see if it all resets

I'm not gonna look up the codes for ya, nor can I remember exactly what my codes were when this happened, but I did run into this problem when I had my ranger.

It started with hesitation on certain speeds with low rpms, then a few weeks later the check engine light came on. Things went downhill fast from there. No power on accerleration and sometimes just bogging down while cruising. I got the codes read, and something about certain cylinders misfiring. I gave it a tune-up(all new plugs, wires, etc.) with no luck. I then purchased a new coil pack, and it was back to normal. A few weeks later another code came up. My cats were clogged because of the misfiring.

So maybe the coil pack? Don't let it go too long like I did
otherwise you will end up spending another $200 to have your cats replaced..

I had a similar situation to yours. Turns out I didn't plug my MAF connector back in after taking it off. Check your MAF.
