2.3 idle
 

the idle speed on my 89 ranger (150,000miles) has been hanging up alot lately. Regular warm idle speed is like 550, but it hangs at like 900. I have read that on high mileage vehicles the butterfly shaft will get worn and physically hang up - is this true. I've heard that setting the idle up a little can cure this (which I would like to do, because I like a higher idle anyway) Why does it say idle speed not adjustable - because of emmisions? Need some ideas?
(I have cleaned the TB and it still hangs)
thanks

Check your idle air bypass valve, and the egr. Also might wanna check your TPS voltage. Plus, you might be able to adjust the idle at the throttle linkage.
