P0300 Chevrolet -

Question

I was driving in the freeway my car was running smooth like usual and out of nowhere the engine light came on so I pulled over and once I stopped the engine stared making. A noise and also shaking and so I turn it off I tried starting the car again but I wouldn't start anymore . I have a 2010 chevy impala LT. When I plugged in the detector this is the. Code that's showing p0300 they already changed the spark plugs and still the car won't start and instead it bend the new spark plug.

Answer 1

HI there,

If it's hitting the spark plug that indicates internal engine problems. Possibly something has broken off the valve and is hitting the plug causing the problem. Sometimes you can get carbon buildup on the valve and if it breaks off it can damage the plug. I would say next step is a compression test.
