Just replaced my idel air controle moter and it already broke

It is not adjustable, it is computer controlled.

Those generally don\'t "break". What usually happens is the get a piece of carbon or a small chunk soot that sticks to the shaft and causes the idle control motor to stick in a partially open position. Take it back off and clean it and re-install it. It will also take the computer a few minutes to reset the engine idle once the new idle motor is installed.

do you have power at the blower? does it work on any speed?check all fuses and relay. also, look into the blower motor resistor, located next the the blower itself

Earl! You could have bought a new car! Ah, but you must love this Ford truck, it's obvious from the never- say- die parts list. How long has this project been going on? If you plan on finishing it yourself. here's my thoughts: Invest in a good scan tool (about $150-$200), a good compression tester ($40), a vacuum gauge ($15), a multi-meter (your choice-a useful one starts as low as $20, a digital volt-ohmmeter (multi-meter) designed for auto electronics is desireable), and last, maybe a fuel pressure tester to round out the list (about $40). Maybe you have all or some of these already. They are all good diagnostic tools you will find very helpful in getting to the root of your problem. The place to start is with the scan tool. Look at trouble codes, look at live stream data. Both will help you a lot. Do a compression test. Find out the internal condition of the engine. New parts are good. Now make them work.

check if all vacuum air OK . check the idel air Beside idel control .check the agr . or you have bad voltage regulator .

You need a coolant temp sensor my 99 did the same thing.
Good luck

Plugged air filter - replace.

Dirty throttle body and idle/air control motor - Can of Carb. cleaner sprayed into throttle body and idle/air hole while engine is running.

If engine is also running rough check:
-Spark Plugs.
-Compression for bad valve.

its vapor locking try leaving the fuel cap a little lose!!!!

I would check your heater control valve, that, or the core itself being bad, are the two most common problems I've had with Chevys.

To be certin of the actual cause you will have to get a diagnostic run on the vehicle..

But from the top of my head,
1.) Check the air flow meter(sensor) this can attribute to idling problems

2.) Maybe your fuel injection system needs servicing, check your gas filter for any signs of dregs, this is a sign of a MUCH needed servicing even if its clean dont rule the servicing out

3.) DNT ADJUST THE IDELING SCREW, this is computer controlled , you will need an autodiagnostic tool(scanner) to help reset the ideling..

I4.) Check the Air filter, This is the primary cause of rough ideling. You can just take it out and see if the performance changes, this is how most machanics check the filter, oh and it also looks dirty.

my money is on the Air Flow Sensor or the Air filter
