I have a 99. Loud pop noise.
After I parked and turned the car off it made a loud pop noise. When I got back in to go there's a loud humming noise coming from under the hood. It revs high and vibrates in the front end.
Go have a look. Check your belts. Theres a water pump with a belt on the backside (opposite of the pulleys) of the front bank cylinder head. Definitely check that belt.
