Question about 1993 Oldsmobile Cutlass Ciera
Hi and welcome to FixYa!
Regarding the engine cut off during acceleration I do suspect that you have a faulty MAF (mass air flow) sensor. If the MAF is faulty the engine dies during acceleration which you have to floor or lightly depress the pedal for it to run that too much may make the engine die. The MAF has big contribution on engine performance specially on the idling and vacuum supply.
I do suspect that you have a faulty PCM (powertrain control module) too. One good reason why it does not register the fault code during diagnostic. If the PCM is faulty it may not give power to the MAF which may result to engine failure. Please have this two checked and replaced if necessary.
Hope this helps and thank you for using FIxYa!

It sounds like you have a loose connection to you coil packs. The speed sensors actually could be causing the problem also. If they are shorting out and shorting out the ECU then the car would die. And if they are just momentarily shorting, then it would cause this exact problem. When the car dies going down the freeway does the speedometer jump or the transmission act up?
