You don't. You cannot adjust the idle.If you are having high idle it is due to a clogged EGR valve. You can clean it/have it cleaned or better yet, put a bottle of fuel injector cleaner every other tank of gas OR use Shell gasoline religiously. The Shell V-power premium is best but regular still has cleaning power. This will solve it. I promise.
the engine runs at a faster rate than when the idle speed is lower.
The idle speed on a VW Polo is regulated by a Idle air control valve. The valve is located in the engine bay and can be adjusted through to either increase and lower the idle speed.
No you cant it is controlled by the the cars computer which is set by the manufacturer
Due to the electronic fuel injection system in the 1997 Dodge Neon it is not possible to lower the idle speed. The engine control system computer adjusts the speed automatically.
You adjust the run and idle speed with the governor wire...loosen the nut and adjust it.
There are a couple of reasons why a 1986 Isuzu will not idle. One reason could be the oxygen sensor and another reason could be in the fuel system.
Check idle speed rpm & adjust higher if lower than it should be. Mixture if it isn't.
The idle speed on a 2001 Honda Civic is adjusted through the idle air control valve. The valve is located behind the intake manifold. Open the cover using a screwdriver and tighten the valve to lower the idle.
Idle air control actuator is probably bad.
There is a little screw on your carb, should be on the right side(assuming your vehicle is carbureted)get a knife and slowly turn the screw to lower and raise your idle.
You can adjust the idle from the throttle body. Replacing the throttle body might have accidentally change the idle speed. The idle speed adjustment screw can be turned either way to raise or lower the idle.
Does not have one. Idle speed is controlled electronically through an idle speed control module.
