I tried using the search feature but I couldn’t find anything related to my issue BUT anyways. My 92 Ranger is getting stuck at 5k RPMs when I start accelerating. It idles fine and the throttle body was just cleaned a few days ago. It was driving fine when I parked it about 6 months ago. I’m thinking it could be the throttle cable but I’m not 100% positive. I’m not getting a CEL or anything when it happens.

 

Welcome to the forum

From description it would be a mechanical issue, so yes, could be throttle cable or broken throttle spring, even throttle plate shaft.

I assume it idles OK?
If not then you could have a larger Vacuum Hose unhooked, check Power brake booster hose and PCV hose

If the over REV problem starts when you start to open the throttle and it doesn't want to close again then check the spring, there needs to be a STRONG spring on any throttle plate to pull it closed against the air flow the engine is trying to pull in
There is 18-21" of Vacuum in the intake so holding that throttle plate closed requires a good spring

You can remove throttle cable at engine end, hold it up and spray lube inside it, then work the cable part back and forth.
There is no spring in the cable or gas pedal, the spring is only on the throttle plate, so cable should slide in and out easily.

With engine OFF, open throttle plate all the way, and let it snap closed, should not be sticky at any point, and should have good spring resistance to snap closed quickly.

On the opposite side of throttle body from cable hook up is the TPS(throttle position sensor), it could break internally and cause the throttle to stick open, not very likely, so the very very last thing to check and ONLY if throttle sticks when you manually moved it
