2005 chev cobalt sputters when at idle.

Asked by Mar 23, 2010 at 12:41 PM about the 2005 Chevrolet Cobalt

Question type: Maintenance & Repair

cobalt sputters at idle like it is going to die.  Replaced the knock sensor but it still does it ( now more often)  this happens when engine temp is warm.  Do I have to reset something?  The car runs at 194 to 198 degrees.

You might try cleaning the air intake valve. I had the same problem and it worked for me.


my 2005 chevy calbolt is doing this same thing drives great just idles rough and goes to die when you go to stop and you have to hold the brake and the gas at the same time or it will die


the dealer just told me that it was the throttle body causing it so we are going to get one now and ill let you know if that works
