I did look into tumble flaps. Mine have some noise, but still unsure its the real cause of my problem. The car continues to run like total s*&! I did notice one of the plug boots was a little melted where it meets the coil. New boots on the way. also...here is a link to the odd noise under load. I still think it could be a bearing.
