What is your question?

I changed my mass airflow sensor yesterday the code came back on today and I reset it, does it need more time to calibrate or is it a different issue? Do you have any opinions on this issue?

What makes this problem better or worse?

The issue seems to pops up after the engine is warmed up

How long has your 2004 Volkswagen Jetta had this problem?

A few months
