    same problem. Make real sure your radiator fluid is totally full. I found that the intake manifold gasget had got so hot it curled up at the top corner tip. allowing air to get in unregulated. also check to see if your air intake tubing has NO leaks or cracks between your mass airflow unit and throttle body.
