SOURCE: 1984 Toyota tercel wagon

Although this isn"t a proper fix, and may affect emissions, I ran accross this problem on a friend's 87 2wd wagon.

There is a dashpot that controls a lever the Idle set screw is on, I am guessing it is a decel valve that closes butterfly when coasting in gear. I never looked at a manual to figure out what controls the vacuum valve that is on the passenger side of the engine compartment, but if you disconect the vacuum line and plug it that lever will not back off and idle will remain where you set it with the adjustment screw.

Make sure the engine is warmed up and not on a fast idle cam before adjusting idle.

The car is a 5 speed, I not sure if automatic cars are the same.

The car idles fine now and still run's great and gets 37+ MPG with 240000 miles!

If you want to fix it properly you would have to diagnose why that dashpot is being actuated at idle

SOURCE: how to adjust carburator of toyota corolla 1991

Try to look for a screw 'stop' for controlling the angle of the opening of the throttle plate on the carburetor. Adjust this screw to keep the engine from stopping while at idle.

My 2000 Toyota Echo will not let me put on air or air conditioner idles high at low speed and at park or stop?


It is normal for the idle to increase when the air con is switched on. There is a fuse in the engine compartment - I-UP (idle up)

Carburator and idle problem


Believe it or not you just said the solution to your own problem manufacturers specs requires for any adjustments to engine idle or other carburator adjustments to be preformed while the engine is idling and at normal operating temp in plain english let the car warm up then make your idle and mixture adjustments if this doesnt solve it i would check the auto choke and make sure it is opening at normal operating temp hope this helps good luck

Idle getting high when aircon is turned off


there should be a sensor that bumps the idle up when you load the engine by turning the air/con on
if this is unservicable the rev,s will stay high when air/con is off

Mitsu Montero Sport '02 engine stalls but not when air cond is on.


hi there. the reason that the engine idles good when the air-con is engaged is that ussually all vehicles nowadays have a vacumm advance mechanism. this is triggered mainly by a electric solenoid valve which is also attached parallel to the source supplying power to compressor. a small vacumm hose with a diameter like a common pencil or ballpen case. its made of rubber and it runs from the alternator vacumm pump then to the solenoid valve and to the vacumm advancer unit attached to the injection pump throttle. this system raises the idle a tad higher.

if your montero runs completely normal and you experience no other problems with your engine except for your present problem, then the solution is just raising the idle a little higher. if your montero is equiped with a RPM guage on the dash, try adjusting the idle to around 800 rpms. it would be healthier for your car if the idle raises a bit when you engage the air-con because this would compensate for the added load on your engine.

hope this helps.

1986 toyota pickup starts wont stay running


It seems there is some kind of air entering the carburator where its not required to do so or the idling soleniod switch is malfunctioning, thus not allowing the air to enter for the engine to idle .
Also recheck the vaccum pipes if they are correctly refitted per the schematics under the hood.More over remove the idling switch and blow some air to the hole probabley theres some kind of obstruction over there .

Good Luck.

Engine wont idle unless you keep your foot on the gas pedal


First, try a new accelerator pump. They're less than $10 and easy to install. On the side of the carburator, near the linkage. It's simple a small rubber diaphragm.

When the engine is running ragged, place your hand over the opening of the carburator. If the idle smooths out, you have a vacuum leak somewhere on the intake system; it could be the base gasket for the carb, the intake manifold gasket, or a broken vacuum line, or a combination of that. What you have is too much air getting into the engine, but the air is not going thru the carb. Please check for vacuum leaks, you can use a can of carb cleaner, spray the intake manifold, if the idle smooths up, that would be a good place to start.

Engine won't idle


The Idle Air Control (I.A.C.) valve is bad. This allows the vehicle to idle with no pressure on the pedal. Replace it.
