94 ranger revving up

Hey guys I need a little help cause im stumped. I have a 94 ranger 4x4 with a 3.0 V6. Its doing this funny thing thats really starting to annoy me. Awhile ago it would tach way up to 3 or 4+ thousand rpm's when you push the clutch in to shift. It doesnt matter which gears your between and if you tap the gas it will just tach higher. The ony thing that will stop it is to let the clutch out and that doesnt usually work or shut it off. When you start it again it will run fine for a minute and then act up again. I took it back to where I bought it and they replaced the idle air control sensor with a used one off a taurus. So i drove it and it worked fine for a couple of weeks then it did it again. So I looked under the hood and there was a rock in the throttle linkage so i took that out and it ran fine for a month. Now it is doing it again and I dont have a clue what it is. Any ideas anyone??? Thanks

You need to run a KOER (key on engine run) test on the computer. It will have a code and check back with the code.
