Just purchased this Malibu for a friend. It drove fine for the 200 miles I put on it before taking it to him. I drive hybrids and wimpy cars so I don’t have a heavy foot. Oil and fluids looked good before delivery. He’s a bit younger so he might have floored it or been racing it down the roads who knows. When I got the call at first I thought it was the worst a cracked piston because he said it misfired home and when I got there it wouldn’t crank or even read the OBD2. I came back and this time the tool turned on and It read all of these codes. I cleared them and the car fired right up with the same codes. My conclusion is it jumped timing? I wanted some input on this and see if I’m headed in the right direction. It also seems like no one has made a complete timing chain kit for this model yet. The car has 78,200 miles.
