I have a 2013 g37x with 70k miles. My right motor mount has been badly damaged for about a month (I know why would I wait a month don’t ask). But since it’s been damaged my car has been having heavy vibration when idle and when I push hard on the pedal it sounds like it’s hitting metal to metal. I took it to my mechanic and he was accelerating while braking and it triggered the check engine light to cut on. There was a delay in response when he would accelerate my car. I got the car at 53k miles and never cleaned the throttle body, never changed spark plugs, or really had anything done to it besides oil change and brakes. Also my car has been pushing forward a little when braking which causes me to brake a little more so my car can come to a complete stop may be brake fluid not sure but that hasn’t started since the check engine light has come on. A code also popped up P010C. I’ve ordered oem MAF sensors (2). Also ordered z1 motor mount kit. Can anyone tell me what may be wrong with my car. Or have experienced the same thing

 

This is a shot in the dark,
but knock sensors have been known to misinterpret rattles and thumps. This would cause the ecm to pull timming and/or "limp".
loose motor mounts are also known to take out wiring harness and anything else in the way.
double check ALL your mounts, bushings and dampers.
suspension components too
