Help! 2007 Chevy Cobalt LT 4door Sedan, 2.2 4cyl, Automatic
I'm having issues with my 2007 Chevy Cobalt LT 4door Sedan, 2.2 4cyl, Automatic.
First off; my major problem is the misfire in Cyl 2, throwing the code P0302, which isn't much help because I have replaced Coil packs, Plug after plug. Also, the Traction Service Light is on, My next thought would be to replace or have the valve head cleaned. When the car is in idle, it shakes, then once it you accelerate, going into second it jolts, then gets power from second on. It does make a slight jolt going into third. Keep in mind it is an automatic. Also, my muffler goes "PUTT, PUTT, PUTT, PUTT..." Yesterday evening we did take the throttle body off and cleaned it, MUCH better performance, but still the shaking while idleing and the kind of jolt when switching gears upwards. We have noticed many times after changing the air filter that the old one looks as if it's getting water in it, because it is sort of the light brown color in certain spots. Does anyone know what this could be?
Secondly; My air conditioner...I am not getting any air from the vents, nor defroster. I just replaced my Blower Motor, Blower Motor Resistor, Blower Motor Relay Fuse, still no luck..but you can tell that the Blower Motor is kicking on. Also we noticed the connector for the Blower Motor was melted to the old Blower Motor, with replacing the connector, that leads me to believe it is the Wiring Harness. Is this correct? Is there another fuse I should be looking for? Or anything else?
Willing to try anything, just don't know if we're looking over something. Thanks in advance!
