1968 car idle very high when started in park?
Your car will idle high until the engine begins to warm. You could set the idle to be a bit lower, but that may cause the engine to stall out when it's cold out. The engine should begin to lower the RPMs when it is warmed up.

Why does my 2001 kia Rio vibrate when i am stopped at a light for example the car shakes through the steering wheel it's coming from the engine the vibration stops when i put it in neutral?
It is the Throttle Position Sensor. I also have a 2001 Kia Rio and my car has been doing this since last year. Brought it to mechanics in the city and no one could figure it out. A backyard mechanic figured it out for meMy car will idle high upon startup and then stall. It once took me 7 startups before I finally got it going. Also, it will begin to stall once you hit the accelorator just after startup. The idle is so high in my engine that the vibrations are annoying on the arms when car is stopped at lights, etc. It's very embarrassing when other passengers are in car. Neutral makes high idle go away. High idle will also "break" into normal idle occaisonally then go back into high idle when car is stopped. Car will also violently jerk upon hitting accelorator for merging purposes.
Where is the fast idle screw on a 2001 ford escort or how do you adjust the fast idle?
It is very likely there is no way to adjust the idle on your car. If your car is idling low, it's probably a problem somewhere else. Idle is likely controlled by the computer.
What would cause the engine to idle very high and then it stalls out but if you give it some gas you can keep it running but again at a high idle?
Check the alternator.
