The CEL has been coming on intermittently.
Got hold of an Innova 3030h scanner and got the following codes/descriptions:

P2188 Fuel trim rich at idle bank 1

P0101 Mass or volume air flow circuit range/performance

Any idea what could be the cause?
Next steps to diagnose?

Fuel trim rich is because of the P0101 code. It could be the MAF needs cleaning/replacement, OR, there is a vacuum/air leak after the MAF. I would look for a loose connection before opening my wallet for a new MAF.
