Hi Alexandra, Im AL the owner of Big As Auto Repair

There are several things that can cause high idle, but the 2 most common problems are as follows.

(1) You could have a vacuum leak somewhere on the engine. Here is how to check for that issue. Here's what I want you to do: Buy a can of CARB Cleaner and while the engine is running spray around the Intake Manifold, the manifold is the thing the throttle body sit on. Also spray around all the vacuum line as well. If while spraying there is a change in the idle speed then you have found your leak. If there is no change then move on to step 2.

(2) Sometimes when you have a high mileage vehicle parts begin to ware out or can also begin to stick in place. Here something you can check. Idle Air Control Motors can start sticking from corrosion build up and can cause a high idle issue. Here what I want you to do. Start the engine and let it idle, while its idling I want you to tap on the Idle Air Control Motor If it idles down to normal idle speed replace the motor. The motor mounts onto the throttle body and most of them are round. Once you replace it and start the engine you'll notice that its idling real high, :This Is Normal, just let it idle until the engine controller resets the idle speed to normal.

Hope this helps and should you need further help please visit my auto repair website. http://www.bigasautorepair.com/

A stuck idle speed control motor ! Tap it with a wrench or something similar , You'll find it located on the throttle body ! Ford IAC valve test how to adjust minimum idle speed

Sounds like your AIS (Automatic Idle Speed) motor is working sluggishly or intermittent.
Try cleaning the throttle body and/or replacing the AIS motor.
I used to see that a lot working at the dealership

Here are the most common causes of idle surge, rough idle esp when cold and stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

Could be a faulty idle air control valve.
The computer controls idle speed by regulating how much air enters the throttle body thru the valve.
You could unplug the valve when the idle speed is close to normal, then shut the engine off and restart to see if the idle speed is still in the same place. Unplugging the valve will also set a trouble code and turn the warning light on.

Idle Speed Solenoid or Idle Speed Motor.
Screwed onto side of throttle body, easy to clean or replace,yourself.

check and make sure air filter is ok, and there are no restrictions in hose to throttle body, check iac (idle air control.

it sounds like you have a vaccume leak you need to get some starter spray and while the truck is running you need to spray it on the vacume lines and when you spray it and the idle get better the means thats where the leak is and you need to replace the hose

The high idle is caused by the choke and the high idle on the carb. It is working normal and you do won't to warm up this motor before going. When it is warm and you hit the gas it activates the choke pull off to bring the idle to normal. Your mechanic is used to fuel injection that will control the fuel/air mix according to temp. I still let my injected cars warm up so the oil can thin a little. If you jump on the highway with cold thick oil it can all wind up in the to of the motor.
