Help, 5 grand idle at idle. wtf???

[Goldstreak]

92 240 with Ka24deWhile driving down the road last week, the car started picking up speed on its own. Revving between 5 and 6 grand. I have since replaced the tps, replaced the O2, and temp sensor. I have also cleaned the maf, and the throttle body. I have also adjusted the idle. No good. The car is stuck at an idle of 5000, unless I give it gas, and then it sticks at a higher rpm. Please help.

computer?.... pretty confident

look for a giant vacuum leak or posibbly something stuck in your throttle body.

Thanks for the ideas. I have already checked for vaccuum leaks, using tb cleaner, and have completely cleaned the tb, itself. One thing I haven't checked, was the computer. I was kind of hoping that wouldn't be the case.
