    vaccum leaks will casue high idle, if u have a leak you can alwasy spray carb clean around the intake and vacuum lines if u notice a change you def have a leak not all can bee seen by eye. change your iac valve

Volvo v40 2000nx reg 1.8 NON gdi engine constant high rpm can having no thermostat cause constant high rpm or can a briken lambda sensor cause high rpm cleaned all throttle body cleaned idle valve checked...


Yes, having no thermostat can cause the car to run fast as it will still be set in it's "warm up" mode and will be injecting a richer mixture of fuel/air into the cylinders. There may be an additional cold start injector that just works while the engine is cold. You will probably use more fuel like this. It's not a great idea to run with no thermostat anyway because you get uneven hot and cold spots around the engine which is bad for it. Cheers

The fuel pump was changed,now it idles high.


The idle speed is controlled by an Engine Control Module (ECM).
It needs to be put on a computor to be checked.
The idle air valve provides the control for constant idle speed. In order to set the correct air valve opening to achieve constant idle speed, the fuel injection control unit uses information from the air mass meter, A/C switch, throttle valve switch and the ignition control unit (RPM signal) to regulate the output current to idle air valve. This means, there is alot of things that can make the idle speed go up or down...Hope this was some help to you??

Look for a vacuum leak somewhere. This is the most common problem for a high idle.

Idle malfunction


You need to replace your idle air controller (IAC). IAC basically opens and closes the throttle at idle so it stays at constants RPM.  Hope this helps.  Thanks for an honest rating and for using FixYa.

Engine starts,reaches high rpm,then slowly returns to a rough idle, misses badly,no backfire,surges as if searching/adjusting air/ fuel/est,timing light shows mark constantly changing/erratic,engine then...


Vacuum leaks. Check all hoses and intake bolts. Leaking EGR or plugged PCV valve. Air filter plugged. Leaking head gasket. Worn timing chain. Camshaft lobes worn. Valves burned or leaking. Fuel idle control system or sensor. Good luck!

Idler is too high on start-up, goes up to 2.5-3 rpm. and comes back to normal. just started a week ago. what could be the problem? 2005 Chevy Aveo


I bought my 2004 aveo 49 miles. I've had several issues with the car. But recently I been experiencung high idle at start up and clutching. I change IAC. Plugs and wireds. Nothing worked. Today the high idle became constant. It was a metal bubble flex tube near the IAC unit that goes to the exhaust stuff down behind the motor. It apparently was cracked cause today it broke causing the constant high idle sound like a vacumn. We blocked it off with a stick to get the idle back down to 900 rpm instead of 3-4000 rpm took we can get to auto zone for high temp hose per Chevy dealer. I hope this helps someone cause it was fustrating and costly.

Runs erratically


The idle air valve (located below the throttle body) provides the control for constant idle speed. In order to set the correct air valve opening to achieve constant idle speed, the fuel injection control unit uses information from the air mass meter, throttle valve switch and the ignition control unit (RPM signal) to regulate the output current to the idle air valve. This means that the idle valve is not affected by air leaks or a jammed throttle valve.
