Thanks for all the responses. I checked the cables and did not find any problems. Since the throttle hang fix is so easy and inexpensive, I tried that and the fix seems to be working. I have one problem with the throttle hang fix. Now when I start the car in the morning, the cold idle revs at 750 instead of 1,500. Other than that, the car idles fine and the car's throttle problems have gone. I wonder if the throttle hang fix only cures the symptom and not the cause. I wonder if the problem is the idle control valve and replacing or cleaning that component will fix the throttle problem. Is it good for the car to idle at 750 RPM when the engine is cold?
Thanks,
