    This problem has been plaguing my 2010 automatic cobalt LT for a couple years now but has steadily grown worse, here's what I know: The original symptom was the speedometer jumping at idle (not rpm). Initially, this wasn't an issue and I just dealt with it. No CEL. I have verified the light...

    I have been having an issue with my car that I am having trouble tracing the cause. It intermittently stalls when I decelerate at a stop sign. This issue has happened 3 times so far within the last 2-3months, but the last two times were within a few weeks. The CEL does not turn on when this...

    Hello, I have been having problems with my cobalt for years now and figured I’d try asking here. Here is what I am dealing with right now. Sometimes while driving, the auto door locks will go off and make the unlocking/locking noise. When that happens the check engine light flashes on for less...

    Hello! Disclaimer, not a mechanic. Just trying to get a bit more life from my trusty Cobalt since now is not a great time to be investing in a new car. Basically, whenever I'm coming to a stop the speedometer may jump up to 30-40mph and the RPMs will spike. More often than not the car stalls...

    So I have a 2008 cobalt, and its winter here and everyday its cold outside my car sounds awful starting like its not going to but does, and if I drive it without it being warmed up a lot she stalls out when I stop. This only happens for the first few minutes until the coolant warms. SO, I...

    I have a 2006 LS 2.2 Coupe and for the past year my car has stalled on and off when I come to stop lights or stop signs. It happened so inconsistently I didn't really worry about it. When the recent ignition recall happened I thought it could have been that since there were reports of the cars...

    Some quick stats; car is bone stock, low kilometers, runs fine, newer air cleaner, new plugs, and, yes, throttle body cleaned out (I cleaned the living fook right out of it and then some whereas it was actually quite clean to begin with). The car is auto shift. The spontaneous mystery stall...
  11. Problems and Service
    If I remove my throttle body to clean, is it safe to use carb cleaner? My other question is will it need to be reprogrammed if I take it off and clean it? What precautions should I take while removing it and cleaning it? I hate to mess my car up! I am a broke High school student!
