So after the head rebuild, I have everything back together. She does fine for the most part except for occassionally out of nowhere the rpms begin to pulse ever so slightly then the car begins to buck slighlty followed by something that sounds like a massive misfire (Ive never heard a sound quite like it before) and a large buck that feels like stalling out leaving a stop. After that sound the car bucks and pulses slightly again for about 30 seconds to a minute then everything smoothes out.
Could my a/f ratio be way off and causing this or could it be potentially more serious?
