If the Check Engine light came on, it set a code in the engine computer that will help to find out what happened. You need to scan your engine computer to get the information needed to diagnose the problem.
I had a similar problem @105k. I had changed the fuel filter but it was still sending all kinds of codes that were related to 2 problems. Long story short, the main problem was a bad trigger assembly in the distributor (rough running) and the other was a loose engine to body ground (engine code issue). Good luck, this worked for me, now 171k.
If it was your cranshaft making that kind of noise.your motor would have frozen up already.it seems more like a tranny problem than an engine problem. Take it to a good mechanic. It sounds like your tranny is about to go.
Can you clarify what is loud , is it a vibration noise, exhaust noise ??
