Hey guys, I heard a slight knocking sound while driving on the highway in my Fiero. The motor is from a 99 gtp, and was supposedly rebuilt at some point. The sound got louder, and right around the corer from work the motor cut off. I wasn't able to get it to turnover again, but I'm going to head over with the tow truck and see if I can't get it to at least turn over. I fear it threw a rod, but I've also read it could be a flywheel related issue. Just figured I'd see what the most common issues are with these, since I was under the impression the bottom ends are pretty bulletproof in these motors. Motor is bone stock, oil looked and smelled fine, and it never overheated at any point.
