yeah I don't have the experience/training to diagnose either
I eliminated the MAF sensor, upstream O2, Spark plugs, and air filter.
Took it to a shop and they kinda bullshitted me on the diagnosis I think
they said to replace upstream O2 but the light came back
unless the MAF is having intermittent problems or something...that's the only one I didn't replace, just cleaned and checked the numbers to make sure it was in range
