Does it run fine other than not wanting to idle right? If so it could be a dirty or faulty idle air control valve and/or dirty throttle body. Also How long since your last major tune up? (Plugs, filters,ect)

I just replace the spark plugs which were hell to take out. I haven't had a tune up yet. Just got the truck on the 24 of December. After I replaced the plugs, it doesn't cut off like it did before.

Also put new filter in as well.

The truck runs fine. Just look like the previous owner did a little mud trucking with it :-()
