Un-do the hose clamp on the air box and the one on the throttle body, carefully disconnect the MAS sensor plug at the top of the hose... remove the hose and inspect it for cracking or breaks. Very common... This condition causes un-metered air to enter the system. The new part is about $80.00 on ebay. It will likely come with a new MAS sensor. JUST BE SURE AND DOUBLE CHECK THE AIR FLOW DIRECTION arrow on the sensor. The last one I did, the part was good but the sensor was installed backward. Took me a while to find that problem.

Fuel pump relay

Run fault codes and check for idle speed sensors/MAF/MAP sensors. If the pump was faulty then it would not supply fuel to the manifold. Test it by having a pressure test done on the fuel. manifold

The throttle just started sticking in my 2005 Aveo. It idles around 2000 rpm where it should be much less. Can I fix it or should I take it to a mechanic?

first off check for carbon buildup at throttle plate, it maybe holding throttle open, you can clean this with carb cleaner and a old toothbrush.clean sides of throttle plate good. then check idleing. if necessary check throttle cable.

2005 AVEO - at idle the engine revs up and down (1000rpm to 1500rpm +-). If it is idling smooth you can turn the AC on and it starts reving up and down. Think I got some bad fuel which began the problem,...

check your fuel cap when they start to go bad the pressure in the tank won't read and it will make it do that. and if it still does it then try cleaning the throttle body and the mass air flow sensor when they get dirty they can cause the same problem

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.
