2000 Pontiac Grand Prix P0300 Misfire: Possible Intake Leak or Coolant Contamination?

Model: 2000 Pontiac Grand Prix Fault Code: P0300 Posted: 2016-07-11 11:21

I'm experiencing a P0300 engine misfire code on my 2000 Pontiac Grand Prix. The issue appears to be linked to a potential intake manifold leak, as I've noticed coolant appearing both at the front and back of the engine. Could this leakage be causing the misfire? Any insights or diagnostic steps for this specific model?
