Last night and this morning I had the accelerator pedal stick as I let off the throttle. In order to get it to release I had to stomp the pedal. The 1st time scared to crap out of me! I was coming up to a red light with 2-3 cars already in front of me! I threw it into Nuetral, the engine was racing for a second until I stomped on the pedal in order for it to release. That was definitely a pucker moment.
I can't pinpoint any pattern to it so far. It's happened after a fast acceleration, normal acceleration and after cruising for a few miles at ~55mph. I took a brief look at it last night and worked the throttle linkage by hand a couple times and didn't notice anything out of the ordinary. Today after work I'll check the linkage cable thru the firewall as well as the rest. I'm hoping all it may be is just gunked up stuff that needs to be cleaned/oiled. Is there anything else that I should check out in particular?
Sticking accelerator

it's a cable style throttle, so just follow the cable until you see the sticking point. make sure the openings on the protective sheath are clean, then look for any frays or cuts on the wire itself.
good luck

Mine does that occasionally but its because my thumb throttle needs the occasional spray of grease. It might be binding by the throttle body where the cable comes out of the plastic. Thats where mine dries out and sticks.

Use a white lithium grease.

Probably got all gummed up sitting for the 2 years it took to get the trans installed.
-
also check the return spring on the throttle body, might be getting old and weak

It's amazing how my Jeep's turned into a recently resurrected old heap found sitting in a cow pasture for the last 20 years...

I plan on cleaning all of the linkage and hitting it with some oil/grease. I hope the spring's not worn! I just bought that reman'd carb a year or so ago. Also, the Jeeps carb'ed... what's a throttle body?
Use a white lithium grease.
Thanks Steve. I didn't even think what type of grease to use or even ask about that. I figr'd WD40 fixed all the parts that are s'posed to move but don't. If I hadn't replaced the valve cover gasket a while back I could just wipe wome of the motor oil off the block and reapply to the linkage cable. -
For cables, 3 and 1 oil works well. You just have to drip it and slide the cable back and forth to get the oil worked in. Takes a while.

Will Lithium attract dirt and gunk up the works? I'm guessing any liquid would do the same. How about Graphite powder? The powder doesn't seem like it would adhere to the surface of the cable though I may be wrong. -

Plastic valve covers, oil caps, most of the pcv fittings are all plastic.
Grease will just attract dust and everything else.

I cleaned and lubed the pivot points on the throttle linkage under the hood, the return spring and on the pedal assembly. I also pulled the throttle cable through the firewall and cleaned the exposed cable pretty well with some brakleen. The cable is sleeved from about 1.5" from the connector at the pedal, through the firewall all the way to the linkage arm. I didn't grease the cable at all bc it's sleeved and it moved just fine. I couldn't get it to stick again so I think I'm good. Time will tell I guess. Thanks y'all for the help!
