Starts okay, but the RPMs fluctuates at times, have this code. Is that usually an indication it's a bad MAF?

Hi,

The code usually indicates a failed or dirty MAF. Also, keep in mind there could be a corrosion issue or loose wire at the MAF.

Try cleaning it first to see if it helps.

Here is a link that explains how it's done:

Try this and let me know the results. Also, confirm the connector is tight, clean, and undamaged.

Take care,
