IAC (idle air control) code. Could be IAC, wiring or corroded connnectors
You don't. If the idle is not within factory spec there is a problem that needs to be diagnosed, such as the idle speed control unit for example.
It is controled by the computer snd should be about 600 rpm. The idle speed solonoid controls it with a signal from the computer. GoodluckJoe It should be 750 RPM after the engine is warmed to normal operating temp.
Once the engine warms up it should be in between 600-800 rpms.
how to adjust idle on 2001 legacy
The idle speed solonoid probably needs cleaning. It is on the throtle body start by making sure the air filter is clean and before removing the idle air control assy, try cleaning the throttle plate and bore with a little carb cleaner. this may fix it and you wont have to deal with all the baloney of removing the throttle body. it will run bad for a few seconds but it will clear....i promise
probably a bad idle air controller.
Why does my 2001 kia sportage idle rough?
The idle is preset at factory. No adjustment provisions are provided. In cooler temperatures, it will take a little longer for the idle to come down. If the vehicle continues to have a higher than normal idle, then you will need to take it to a shop where they can diagnose the problem. Driving around with a higher than normal idle can damage the transmission.
