Well I talked to the mechanic while running the car. Over the phone, he said it sounded bad and advised me not to drive it anymore before it can be checked out. Possible a bad engine rod or so forth. I asked, if that was indeed the case, would it be expensive to fix. His reply "exorbitant." He said it could be something simpler like a loose bearing or something and its best to have it looked at. So now I need to figure out how to get it towed over there, from FW to Dallas, about 40 miles. Very unsettling and if it is super expensive to fix.... it may be the end....
