Engine runs abnormally with idle and middle wheel. 2. Diagnostic unit shows several errors: 3-1-4 and 2-1-4 at the same time all the sensors are OK. Can you give me some advices how to fix this problem?

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 wasnâ€™t solved
