I had a similar problem on my 2002 Impreza RS 2.5 (same engine and engine control system). In my case it was the O2 sensor on the intake manifold. This happened at 34,xxx mi. so it was covered by the warranty. Replacing the part is very easy. (two bolts and a wiring harness). Obviously I would start simple and cheap and work your way to expensive and difficult.
From my understanding its all caused from the engine missfiring. If its been a while or never, I'd change the spark plugs first. (stick with the Subaru Parts plugs, I went after market and the dealer claimed the plugs were not the correct "temperature" and had to pay for the new plugs and install although they did it without my permition. Thats a whole nother story).
Could also be the manifold pressure sensor.
Either 02 or manifold pressure sensor may cause intermitent check engine light.
Where I live Brookline,MA , Autozone will run a free diagnostic on your car by hooking up to your ECU and will give you the trouble codes and possible remidies. Of course there are no guarentee's but it will point you in the right direction.
Good Luck

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: engine lopes at idle and check engine light on

In this case having the check-engine light is a good thing. Take the car to AutoZone and have them scan the computer for codes - they do it for free, whereas a shop will charge up to an hour's labor. Have them give you a printout of the codes, and post them here as a comment/reply. I can help you define them and see what needs to be done.

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 and it wont take gas, it don't want to idle. It misses when you give it any gas or idling. I noticed that my check engine light started flashing. What can be the issue?


First step is to get the computer codes read. Your local auto parts dealer may read the codes for you at no cost. Once we have the codes, we can advise you further.

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.
