MAF codes can set due to the poor running / stalling issue. So the MAF might not even be the issue.
I have had two vehicles in the last couple of months with EPC light / stalling / starting issues. Both were solved by replacing the ECM power supply relay.
Replacing parts isn't the way to go. Have someone monitor ECM data blocks while the engine is running poorly, until the reason is determined.
