'90 GT When you unplug the Mass Air Sensor it will idle, plug it plug and the car dies. Problem 2 has a backfire after you rev it up. Can these 2 problems be link and what could be the cause of them? Thanks

problem 1, stop unplugging your MAF.

problem 2, check your fuel pressure, spark plugs, and O2 sensors.
also, run a KOER and KOEO test for any stored codes

id run codes like before mentioned but yes the maf if dirty will make the car backfire. clean your maf sensor. i had the same problem and troubleshot a while with no luck til i cleaned the maf sensor and that was it. good luck
