Re: i have the same problem as this, car turns off at...
Mcdevito75 here, YES and NO as you most likely won"t do any good. The idle at the carb is usually set at the factory and is controlled by the cars computer thru sensors/ motors, if you turn the screw--s on the carb. you could send a wrong message to the computer and make your idle way out of control, and if your idle is off due to a faulty sensor/ idle motor you again, are doing no good. BEST BET, have your local shop run a scan on the cars computer, check for vacum leaks etc to addresss your idle problem.

The screws are to adjust the idle mixture and speed. They have no effect on the motor at 55 MPH. To adjust the idle mixture
lower the idle speed to the lowest speed and slowly turn one screw in and out until you reach maximum rpm and then move on the another.
Start with the idle needle screw first, the idle mixture screw. Seat it all the way in, first-don't overtighten and damage it, just seat it lightly, and back out two full turns. Run the engine and set the adjustment by ear to get your best lean idle: start turning the screw in (clockwise) 1/8 or 1/4 turn at a time till engine stumbles, dies, or runs rough. Keep the engine running, and turn screw out (counterclockwise) a little at a time till you hear the idle dropping. Now between those two settings is your best lean idle. Turn the screw in, a little at a time and wait for engine to respond, tiill you get the highest idle speed. Now set the other idle screw, curb idle, to the idle setting for your truck, probably about 700 rpm. You can move back and forth between the screws to get the best steady idle. Just don't over do it on the idle mixture screw. Good luck.
check for a small screw that the throttle mechanism touches when you move the throttle, get someone else to open and close the throttle and you will see which part moves. you will only need to turn it 1-2 turns to make a difference( the engine needs to be warm) If the one you screw doesnt make a difference screw it back to where it was by counting the turns.
Any mechanic could adjust the idle in about 10 seconds, and couldnt possible charge very much.
I will start with the easiest fix for you and if that does not work, we can go from there. You should have a carburetor system. On the carburetor is an idle control screw. If you can not locate it, let me know.
You should turn the screw clockwise to increase the idle rpm. If turning the idle up does not work let me know and we can go from there.
If I can be of further help, let me know by calling or email. Please take the time to rank my effectiveness. This is the only way I can improve my ability to help others.
Because it's carbeurated they have an electric 'idle up' solinoid (or vacuume) to compensate for rev loss when load is put on the engine caused by the alternator working harder because your using power. It should have a small adjustment screw on the carbeurator to lower the revs. If you have it set too low it will shudder when in drive & foot on brake with headlights on. It should only pick up about 200rpm when lights are on. To find the screw, take the air filter off, run the engine & look for something moving when the lights are turned on & off. Somewhere near the moving bit you will find the adjustment screw. I hope. I'm not sure exactly where it is on that model.
