I bought my 2009 Chevy cobalt used about 10 months ago! I have not had any issues with the vehicle other then hearing about the recall as soon as I got recall notice in the mail I made arrangements with my Chevy dealership to get it fixed! recently got the recall done on vehicle from my Chevy dealership about two weeks ago and today coming out of work I had a dead battery which I thought was weird because I swear I didint leave anything on and on top of having no power my key was stuck in the ignition ! I then had my vehicle jump started and the key came out fine after that but my check engine light has been on since My car got power back it was not there going in to work this morning! I noticed a lot of people having the issue with losing power and key getting stuck but was just curious if anyone's check engine light came on Aswell?
My passenger front speaker and right turn signal stop working. Sometimes it the same time sometimes only one quits working. The turn signal usually will work if I barely hold it on or if I push it past the "on" position. Also the low oil pressure lightcomes and goes off that matters.
We were told it the problem was the MAF sensor and just replaced that. There was a broken wire to the MAF senor which was repaired. Still having the hesitation in 1st/2nd gear. The engine revs when given gas but transmission does not kick in. Any suggestions? When the MAF sensor is replaced, do we need to "reset" something?
the engine light does not always come on when this happens
starts bucking. i have had the check engine light come on indacating it was the mass flow air censore. chaged it twice. helped for awhile but thats it. the check engine light is now on again and really bucking but we know its not the mass air flow cens. i thought it had to do with humidity in the air because it seemed to act up when its really hot and humid out but it does it all the time now. i put sea foam in the gas thinking that would maybe do something but nothing.every time you shift and it gets at the 2 25 rpms thats when its the worst but it will continue to do it off and on at any speed.
I got this code after takin off and cleaning the throttle body on my cobalt, after unpluggin the the battery for atleast 15 minutes it seems the car idles normal between 800 to 900 rpm but i got this code showing up p0223. would that mean i need a new pedel sensor or is something im missing here?
I changed my oil, cleaned the actuators on top left of motor. Still has engine light coming on and off, but car runs rough at stop light and when low rpms.
When my car is in idle, the speedometer goes crazy and wants to stall. It first started when I turned my AC on last week but even after not running the AC, it still acts like its gonna die when I try to take off.
I had a bad sensor trying to hace car insoected.replaced part now i have driven tomwo hundred miles and evap semsor and another are still not ready
While sitting at traffic lite eng would feel like lurching or misfiring to the point of almost stalling but so far not stalling, also the check engine lite has come on and then off a number of times
my 2009 chevy colbalt will only go in reverse and the check engine light is not on do i need a trasmission or could it be something else?
