You don't. The computer will adjust it self for the adjustment you make. Check the computer for codes. You maybe have a code in it; or need to check tps sensor.

My 65 mustang stalls whenever i stop then it starts right back up


Hello Larry,

Without the car running... You should be able to open
the throttle.. and literally DROP it back to idle...

Observe the action of the THROTTLE RETURN
DASH-POT
T should visibly SLOW the RETURN
of the throttle linkage like a door closer...

If you do not SEE the slowess... the dashpot
should be replaced (they are getting SCARCE).

SIX CYLINDER (EXAMPLE (only))

You will need to have the THROTTLE RETURN DASH-POT
on your (unspecified) carburetor
tested and adjusted... and the IDLE SPEED correctly set.

Idle Speed and a slow rate of RPM reduction is
critical to the proper function...

Some LESSOR "mechanics" will attempt to raise the
IDLE SPEED to compensate for a malfunctioning
DASHPOT... This will PROFOUNDLY exacerbate
the problem.

My aveo 2006,engine stalled when air con cuts in at idle after driving..?


Engines have an AC override when turned on , to bump up revs to compensate the extra load. This needs to be adjusted, if you cant do yourself , a qualified mechanic must do it.

94 nissan altima won't start and iddle after cleaning IACV valve


An IAC (idle air control) motor is designed to adjust the engine idle RPM speed by opening and closing an air bypass passage inside the throttle body. The cars computer or PCM (powertrain control module) receives information from various sensors and will output signals to adjust the idle air control motor in or out to adjust engine idle speed by controlling engine idle air. An idle air control motor can fail one of two ways, either the motor short circuits and stops working or the motor will develop high resistance and cause the idle air control motor to react slowly, either failure can cause the engine to stall at idle. When a trouble code scan is performed it sometimes won't always detect a failed or weak idle air control motor.

My 84 ford falcon with auto trans was revving very high while idling now it does rev at all while idling im not used to an electric choke


You were a bit vague in your problem ( now it does rev at all while idlling) Did you mean it doesn't rev at all now, Answer: 1st check all vacuum hoses from brake booster to carby if one of these has come off it will cause it to rev high, Do this before playing with your choke or carby. also check to see if the Carby is bolted onto the manifold tightly as they can rattle loose causing a vacuum leak there. Have you touched anything before this problem occured?

My air condition works but when i turn it on my rpm goes down y is that ???????


The air con draws a small amount of power from the motor.When its turned on,the revs will drop.If the car is an auto,there is an up idle switch/sensor attached.What it is meant to do is bring the revs up just a small amount to compensate for the air/con.Manual cars have the same thing but set up just a little bit different.If the car stalls,get the idle up switch checked or adjusted and all should be ok.Hope this helps you

How to adjust idle on ford falcon el 6 cylinder


wam the car up, disconnect the idle speed control valve wiring plug (idle control valve sits on top of the throttle body) then set the idle to 700rpm with the grub screw stop just above where the throttle cable fits to the throttle body. Reconnect theidle control valve and you're done. It may take a few k's driving for the ECU to relearn the new throttle stop position. The idle speed control valve is only used by the ECU to add idle speed when extra load is put onto the engine such as power steering or air con use, the base idle is set mechanically on the old falconns.

My 01 Accent cuts out on me when I come to stop and dash board lights up. But vehicle starts up with no problem. What causes the car to die?


It may be that the idle speed of the motor is set to low.A stick shift should idle at about 600-700 revs,an auto at about 750 revs.If the air con is used there is an idle/up device that brings the revs up a fraction because the air will make the engine idle slower.the problem may just be a small adjustment.Hope this helps
