I don't know about your trany not shifting since it isn't controled by the pcm on a 93 from what I understand. but about the popping, it could be your opti, or more likely your cap and rotor, but it could even be another sensor.

It's not your tranny. If it was the trans, the motor would run fine. Was it raining out the day you went to start it? Could need wires, or an opti from what it sounds like. Any SES light?

Scan it for codes and see if you get a new one. That can usually point you in the right direction. BTW, my stock opti failed at 104,xxx miles.

my opti failed at 38k. Do a tune up and go from there. Also if you have a ses light on, wouldn't it make sense to have it checked out before you start throwing parts at it.
