The possible list could be a mile long.
Have you checked the engine oil level?
Is the Malfunction Indicator Light showing?
When was vehicle last serviced/tuned?

Thank you for the reply, oil level is fine, no light is on and it was serviced around 6months ago. When I acelerate while in park, it pops, spits it like mis fires. If I put it in gear it kills it. It is really loud.

Seems like misfiring and most likely to be ignition related. Have the spark plugs, ignition coils and wires checked.

If you don't have overheating and coolant losses issues, you shouldn't have blown the head.

You're welcome.

You would still need to have it checked to know what is wrong.
