First off, 92 and 93 LT1's don't have crank sensors.
I am not a fan of the O2 sensors being the problem, but its not a bad place to start. I am a fan of Denso O2s. Hate Bosch. Junk.
I am not betting on a bad ground wire. If so, it would run poorly all the time.
I agree with checking temps, however, if the temp sensor on the waterpump fails, it throws a code, H15.
Which leads to the final question: Does the SES light come on at startup? If not, then the bulb may be blown.
