Jus saw your follow up question.
The MAP sensor replacement does not require resetting of the ECU.
Do you remember what was the code number?
Many times that MAP sensor codes come up for other related issues.
I have attached the complete diagnostics for that code, including step by step guide.
This should help you figure out the issue.
Please let me know of any questions.
Thank you.

Yes, it still could be a bad MAP sensor. We have seen replacement parts not functioning properly out of the box.
Let me know what you find.
Thank you.

If the MAF has not been cleaned in a while it is a good idea to clean it. But it might not make a difference.
