Are you sure it is a 1993 tranny they installed?

It has to be a 1993 tranny only.

I am not sure if it is 1993 tranny or not. I did not have much choice and in case it is not , can I fix it now? Should I change fly-weel, ECU or Ignition Unit?

I believe it is something with the sensors on the tranny.

One more interesting thing: when I switch off the Mass Airflow Meter, it seem the engine runs normally, also I tried to install several types of Mass Airflow Meters but problem wasn’t solved

Unplugging the mass flow won't kill the car that is normal.

A massflow sensor will not fix a tranny problem.
