I would agree with this. It's likely the MAF code was just stored (already present) before the incident. The CPS is a known failure point and your symptoms match it perfectly. And you're right, it is exceedingly rare for a bad MAF to cause what you describe.

CPS is inexpensive and though it's a bit tight back there, this is a simple DIY. And on that engine, it's easier than doing the MAF, too.

Good luck.
