Throttle sticking

No I'm not on the interstate steady picking up speed.

If I leave my jeep to sit overnight, when I come out in the morning the stupid pedal is "stuck". I have to press on it a bit to break it free, then it seems to function without issue until I leave it sit overnight again.

Thoughts on where to spray some lube?

Have you checked where the throttle cable attaches to the throttle body linkage to see if it's the throttle body butterfly valve that is hanging up or the throttle cable itself? My first guess is the throttle body is dirty inside & its butterfly valve plate is getting hung up in dried black gunk inside the throttle body.

Sounds to me like you have moisture in the throttle cable and it is freezing overnight. I have seen it several times in parking cables as they sit under the vehicle and will pick up moisture from the road while driving. Do you ever notice that before the vehicle warms up it is still a little stiff? I would also pull the intake from throttle body and check for build-up.

I did not check that, but I will as soon as I get home. I did clean the throttle body prior to parking her in the garage for the winter, but thats no guarantee that I didn't miss something or create a "blob" of goo thats catching it.

As soon as it "breaks free" its easy as pie cold or hot. Is there a way to get some lube/spray inside the cable? Slow going spray, move back and forth, spray, move some more, repeat 8 billion times?

If it is moisture in the cable I would just replace the cable.

yes take a short piece of fuel line split wrap it around the cable sheath and cable after you remove it from linkage next stick the red tube from your ( pb blaster...best ),wd40,
ect next use a few zip ties to seal tube and cable in hose so pressure will be forced in and thru cable next put rags around cable end in jeep cab next spray away till it makes it thru cable.

you will be amazed at how much better you cable moves.
