top of engine cover back side all the way to your left it screws in and hooks to a vacumn line
AnswerStart with the basics, vacumn hoses, ignition parts, fuel filter/line leaks, sensors. I'd start with Vacumn hoses then fuel...**I have a 92 Chevy Blazer doing the same thing. It's been buggin me for weeks. Afer checking and or replacing the EGR valve, IAC, vacuum hoses, plugs, wires...I am about to change the fuel filter next, but I really suspect the problem has something to do with the exhaust.
Most times - new rubber vacumn hoses, sometimes new plastic hose connectors. A bandaid will work also if you have found the leak.
I would say a vacumn leak. Check hoses, measure vacumn with running at idle and at idle when brakes applied. This assumes you have power brakes and it idles well without the brakes applied. Please make sure that the clutch is working properly... Does your clutch work properly?

When you accelerate it probably does not quit blowing but rather blows out the defroster vent. This would indicate a vacumn leak or possibly a bad vacumn check valve. The check valve is located in the vacumn line that goes through the firewall somewhere between the firewall and where it connects to the engine. Check the vacumn with a vacumn guage (pump) in line going into the dash for vacumn leak. Hope this helps. Keith

On most all cars you have a selector control on the dash for selecting the different options such as floor, defrost, panel, mix, and so forth. This control depending on the car operates a flap/s near the heater that sends the air in the direction you select. Some use a cable to do this and others use a vacumn switch connected by vacumn hoses to a vacumn operated valve that opens and closes as you select. If any of these parts coming from the selector controll goes out it could cause the problem you described. In most cases I have had like this either the selector controll switch went out or the cable or whats it connects to came loose or broke. EzForJesus Check for a leak in the vacuum hoses under hood of car.
Seldom, if ever, do i see a bad intake. On the older aluminum V-8 intakes in the oldsmobile engines they used a steel intake gasket and the steel would corrode pits into the sealing surface which caused antifreeze leaks. Most of the troubles that i see with intakes are with the intake gaskets going bad or with vacumn leaks caused by split vacumn hoses or a leaking intake gasket.

No. The last model of the Chevrolet Aveo was in 2012. The Aveo is now replaced by the Sonic.
