The engine light has come on and it tested out that the mass airflow sensor was at fault. I've replaced it and reset the code and it comes back on again. Any suggestions?

I'll have to go hook it back up again to get the nubers, but what i do remember is, it went to the mass airflow sensor.I'll get back with you on that.

If the air mass sensor is working but not in the range of normal then you might have a vacuum leak somewhere.

I use brake clean, spray it around and see if you can get the idle to pick up, or a smoke machine is good too.
