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.

2002 ford expedition rpm not right


DId the Check Engine light ever come on?? Normally with such a major problem the check engine light should of activated in which case you can take it to a Autozone or most auto parts stores adn they can plug a Code reader into your system download the codes/messages and it should pinpoint or at least point you in the correct direction as to what is causing your issues.
I have had to do that a couple times with my 2005 Chrysler T&C due to a O2 Issue, and a Catalytic convertor issue.

P2610 code--problem starting--I hate this car!!!


In general terms, if all of the fuses and connectors are ok, the problem is inside the power control module (PCM). Could be a bad connection somewhere from the water problem.
I would take it back to the dealer again for a look at the warranty coverage if everything checks out with the fuses and connections.

When I start up my 2005 chevy aveo, the engine rpms go to 2500 to 3000 and will not come back to Idle. when the hood is up I hear a vaccum leak but I can't find a loose hose.


that is causing the high rpm,there definitely is a vacuum leak.you will have to check for any cracked loose or fallen off hoses without the engine running first then if you find nothing you will have to start the engine and find out the area that you hear the leak and run your hands over all possible areas in that section if there is no vacuum hose problems then its possible that there is a intake gasket leak.in that case what you can do is spray intake cleaner or carb cleaner around the intake manifold if there is a change in rpm then that is the area that the gasket is damaged and will have to be replaced.NOTE be very careful when spraying with the engine running as there is the chance of a fire starting with the hot engine or poor ignition wires

2005 chevy aveo brake light comes on when i shift... why?


your brake fluid is low. I have a 2005 aveo that i took to dealer under warranty and told them the clutch didn't feel right and the brake light kept coming on. they told me they have not seen either issue i complained about charged me 700 dollars in labor and rental fees and sent me on my way. I then proceeded to take it to the used car dealership i bought it from and they bled the clutch and said they got alot of air out when chevy told me they didnt get any. Anyway about 3 weeks later the light was on steady and the clutch began acting funny again. I bled the clutch myself this time and didnt check the fluid level or i would have caught the next dangerous part. On the 2005 chevy aveo hatch back i have with a 1.6 5 speed shares one reservoir for brake and clutch fluid. I was driving along one day down a 12% grade about 2 mile long stretch and my brakes failed. I filled the brake fluid reservoir at first chance i got considering my arm was sore from operating the hand brake for 6 miles or so. the light went out. It will probably come back on as did mine. the leak in my system was a check valve under the brake master cylinder. be careful until you get to fixing it.
