I have a 96 Tacoma and mine started something similar recently. It
started the same time that I cleaned my mass airflow sensor. After
doing a few things to diagnose, it sounds like it's coming from the
catalytic converter. I believe that something is broken inside the cat
and that is where the noise is coming from. As to why it started after
cleaning the mass airflow sensor... Maybe there is more airflow so the
sound is more pronounced. The sucking noise is not always there. The
cat also rattles quite a bit but I'm not sure if that's normal. Very
weird...
