Auto idle in cold weather most new cars do it to warm up engine faster

Check for a vacuum leak. This can cause a higher than normal idle. It can also cause a surge since the idle air control tries to adjust the amount of air required to idle.

could be airflow meter fault or throttle potentiometer should see check engine light flashing if either of these sensors are bad, they can effect idle and engine performance.

Try adjusting the idle/air screw on the carb. With the engine off, turn the screw gently to the right until it bottoms out. Don't screw to tight, it will ruin the seat. Turn it out 2 full turns and start the car. After revving the engine a couple of times,let it settle down to an idle. after it warms up, screw it in or out until you get the highest idle speed. If that doesn't do it, you will need to rebuild the carb.

check inlet manifold for vacumn leaks on engine like a breather or a take off for the heater flaps or even the stepper motor for the idle

there is a wy to limit it on all of them by changing the grade of oil
what you need is a lighter wieght oil!
also get it tuned as te idle is one of the first sings that it needs adjusting [out of tune]

check the relay maybe faulty and overheating

Our 2001 mitsubishi montero xls ran hot and blew a head gasket.We just got it back and it rus great but has a little shimey or puttin when we are sitting at a light,as if it is idle to low.Put it in park and it runs smoother. Idle sensor or throttle sensor got damaged from the heat? Not sure...just thinking out loud! Any other suggestions?
