Fault with the IAC valve.there maybe a trouble code associated with it also./ Go to your nearby autozone or auto parts retailer and ask them to put a scanner to the car....make note of the codes if any are found. the IAC valve i usually locate don the throttle body and can be removed for inspection and sometimes cleaning using a good throttle body cleaner spray and a pipe cleaner brush.

SOURCE: how to adjust headlights on 2006 chevy cobalt

There will be adjustment screws located on at least two different spots surrounding each headlamp. By turning these screws you move the angle of the headlamp. Most shops will do this at a very resonable rate, I say this because improper headlamp angle may lead to a ticket, or at least a warning. To say the least, they have to be at specific angles and heights. Good luck.

I had the same exact problem on my 2004 Colorado (3.5L). Cleaned the MAF sensor (with MAF sensor cleaner) and throttle body/plate - cleared it right up.

Start with the basics. Check the fuses (all of them) with a test light and be sure you have power to each and that they are good. Then be sure that the power lock relay is good by swapping it with another relay in the fuse block. If the fuses are good and the relay is swapped and the locks still aren't functioning, you may have an issue with the BCM. The BCM can be programmed to change the behavior, but if the car has had water damage, or other stress to the BCM (voltage, heat, etc.), it can sometimes damage the BCM and you will need to replace it and reprogram it at a GM dealership.

SOURCE: 99 chevy silverado running rough and stalling.

the problem you are discribing would lead me to belive your fuel filter is clogged which is a simple fix 3 dollar part at any part store or on the worse hand your fuel pump itself could be weak you can open the gas tank cover and have another person turn the truck key to the on position without going far enough to start you will hear a faint whining noise if it is going bad or a louder noise if it is fine Good Luck

SOURCE: 2006 cobalt 2.2 engine, when

You replaced the spar4kplugs but how about the plug boots, these boots are like sparkplug wires and they short out sometimes , with over 100,000 miles i would replace them, also you may have a bad coil . the coil is a complete unit its 4coils in one and may be misfiring, the other problem maybe a dirty throtlebody or bad idle air control valve, you said it runs rough at idle, i would first take it to have the computer scanned to see if there are any stored codes, the computer is always yesting all systems and when it sees a problem it stores a code, this code will tell you what is failing, many autopart stores will scan it at no charge, also if it sees the problem a certain about of times it will turn on the engine light, if you get it scanned and give me the codes i will be able to help you further. for example they may scan it and get a code that reads po302- cyl 2 misfire. this means cylinder 2 is misfiring and then you need to see why its misfiring, it may be due to a plugboot or coil or injector. i would scan it first. hope this helps. good luck.

I have a 2006 chevy cobalt when I went to start it, it started up idled rough then shut off, and keeps doing so why?


There could be many reasons - faulty fuel pump or faulty sensors which control ignition/fuel/ air flow.

Don't change parts in the hope that you'll cure the problem. Give a mobile mechanic a call and get him to do a diagnostic check for you and identify the fault. These guys are usually very good and cheaper than a workshop

I started my 2006 chevy cobalt this morning and it idles really rough and my check engine light is blinking on and off. It ran fine the other day when i drove it


Rough idle, flashing CEL, low power would indicate a faulty ignition coil. A armchair diagnosis would be to replace the ignition coil. You'll have to swap the the contact stems (rubber conductors between the coils and the spark plugs) and the igniter module.

Simple task requiring a 10 mm socket and ratchet, a 10mm box end wrench, a T-15 torx bit with adapter and a new coil pack. Cost around $100 and takes a half-hour.

We have a 2006 chevy cobalt with a rough idle, sometimes dies. We have tried seafoam in the tank, worked for awhile, wondering where the fuel filter is located?


That is split year for fuel filters. If you have one then it's in the back by the fuel tank. It will up alittle in the center.
As far as the running rough; is there any codes in it?

Cobalt not running at low rpm.......


All are possibilities but EGR valve makes the most sense. It's famous for causing poor idling and/or stalling at low RPMS. Best of luck.
