  1. 2006 Cobalt No Spark

    Problems and Service
    I have a 2006 cobalt with the 2.2 in it. The engine locked up so we got the 2.2 out of a 2007 hhr. Everything hooks up 100% except the 2007 version has vvt plugs. I'm not getting any spark and the engine ran fine in the hhr (hhr was totaled due to rear end). We've checked all fuses and relays...

    Problems and Service

  5. Starting Issue

    Problems and Service
    Hi everyone, I am experiencing a starting issue with my 2007 LS (2.2 L61 f23). If I turn the key from off to crank, the car will crank for a split second then stop. On the second turn it will start but sometimes will start at a low RPM and stumble slightly to the normal cat-warm up RPM ~1500...

    Interior & Exterior Styling
    Hi guys! Quick question for ya: I have a '07 LT coupe and need to replace only the front bumper cover, not the bar underneath.

  10. Same As 2007 SS?

    Engine Mods
    I have a 2008 Cobalt Sport Coupe, 2.4L motor. I have done some research and I am led to believe that this is the same motor that is in the 2007 SS, sans sc. Is this correct? Right now it is bone-stock, and I am looking to get a couple of bolt-ons right now (exhaust, intake) but I need to be...
