Ok guys, heres the deal:
05 Cobalt Base - 2.2L
Went to start it up one day and it's spitting and sputtering. Popped on my Code Reader and it popped a P0300 Random/Multiple Cylinder Misfires. My thought was initially the ignition coil. So i change the plugs and Ignition coil. Still doing it. My thought at this point is Head gasket/cracked head.
I start it and rev it, it take a good few second to reach rev limiter. I put it in gear and put the pedal to the floor and it hesitantly goes 1mph. Also in the snow i see little black specks that came out of the muffler, when it was revving. No oil in the antifreeze, and it doesn't look like there is anything wrong with the oil on the dipstick. Let the car run for 5 minutes at idle, and only got a temp reading of 570*F in the cat, and it didn't take on color, so to me that isn't a block. Below is a picture of the drained oil as well. It's not emulsified, but there is something white in it...What could that be?
Could this be a plugged cat or am i looking at something more?
Attached below is some readings from the OBD I took. Does this signify a plugged cat?
