yes, it is very common for used '90-'94 AFM's (MAF) to be bad because many people mistakenly cleaned them with solvent or "MAF cleaner" over the years.
however, 34 is not a valid code for the engine, so could you download the codes again using this procedure?

My next procedures to check will be the following.
- fuel pressure regulator
- fuel pulsation valve
- fuel pump
- ECU (send it to get check) even do there's no signs of melted capacitors or damage on the board.
Thank you guys for your help !!
