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,

Idle between 750 and 1000 is normal. You just have to play with the hole sizes to get the right idle for your car. And depending on the seasons somethines you need to switch to a different hole size, because different seasons bring temp, and pressure changes.

Experimenting is the only way to find the correct size becasue everyones car is different.

Well I tried the throttle hang fix and it worked, the throttle did not hang anymore. But after a few weeks the cold idle got worse (the car wanted to stall in the morning) and last Thursday (1/23/03) the car would stall when stopped even when the car was warmed up. I would have to keep the RPMs up around 2000 when the car was stopped to prevent it from stalling. I replaced the idle air control valve today and now everything works fine. No more throttle hang and no more idle problems. The car also seems to have more power, especially in the mid RPM range. It seems to me that the throttle hang fix reduced power in the mid RPM range. I have no real proof other than the car felt much quicker in the mid RPM range.

I am not saying that all throttle hang problems are the idle air control valve but mine definitely was. I would still try the throttle hang fix first to solve any throttle hang problems since it so easy and cheap and if it works great. If it doesnâ??t, I would replace the idle air control valve next. The valve costs around $60.00 and is also easy to change (not as easy as the throttle hang fix though).

Thanks for all your help. This site is a great since most Ford dealers are really pretty bad, except for you BigJim .
