The idle speed on this vehicle is controlled by the engine computer. If it seems to be idling high, the idle air control valve (IAC) may be stuck or faulty. This can sometimes be corrected by removing the IAC and cleaning carbon deposits out of it with carburetor cleaner. Some sensors can also cause a high idle, such as air temperature sensors or throttle position sensors. If everything else seems to be OK, however, the IAC is the best bet.

Will not stay running at Idle

Clean your throttle body with throttle body cleaner, inside and out, and check your idle air control valve on the throttle body. That can be taken off and cleaned too. Be careful with it, it has a small motor called a stepper motor. It's how the engine computer controls the idle speed. The only air passage into the engine at idle (when the foot is off the gas pedal and the throttle plate is closed), is this air passage under the idle air control motor. The stepper motor allows it to control the amount of air, less for lower idle speed, more air for higher idle. See? Well, good idling.

2004 hilux 3rz engine idles 1200 rpm

For some engines that is a perfectly reasonable idle speed. My motorcycle idles at 1400 from the factory. Presuming that your factory idle is at a more normal 750 or so, and you have ruled out vacuum leaks or accidentally removed vacuum lines it may be that you just need to set your idle lower. If that's your only problem, adjusting this should be easy, just find the stop-screw attached to the throttle body.

How do I find an idle stop screw for a 1993 geo metro?

If it has a stop screw, look on the throttle body assembly where the throttle control cable hooks on- the gas pedal cable running from the lower firewall to the engine. You can rotate the throttle control by hand, but where it is in the at rest position- as at idle-there would be a stop screw on the throttle body, which can keep the throttle control from closing further.

Vechile idles to low

the idle air control (IAC) probably needs removed and cleaned. this is what controls idleing on most vehicles now days. but do not put entire unit in any liquid. use an old tooth brush or similar to clean the carbon from it, also be sure where it mounts is all clear.(use aerosol carburetor cleaner) The throttle body of your engine controls the secondary air intake for the engine. The throttle body becomes dirty with air contaminants that the air filter cannot keep out. This condition is called "coking" and can cause stalling as well as lower the engine idle. clean out throttle body and throttle plate very good. especially on the sides of the throttle plate where it will stick. good-day !

1999 Daewoo Lanos SX is not idling properly even after I canges the MAP and the Throttle position sensors, what could be wrong?

go back to basics
do cylinder compression test, dry and wet
if compressions 25 psi lower than another one this can cause rough idle(valves leaking)
should be 150-180 psi any lower engine wear.
check pcv hose from rocker cover to throttle body especially port in throttle body for blockage.
are any codes being set?

High idle will not lower

sounds like you have something blocking the linkage or the throttle body isn't closing totally or you have a air leak.
