Catalytic IM Not Ready
I just replaced MAF for P0171 last month and after driving over 600 miles the Catalytic IM is still not ready.
The SES has not come back on but I am concerned the Cat IM hasn't reset yet.
The car was running lean because of the MAF and I think the Catalytic Converter is not getting hot enough.
After first trying cleaning the MAF before I replaced it, all monitors set after 3 hundred miles.
Any suggestions?

Over 2000 miles now and it hasn't reset itself.
Should I not worry about it because it will pass smog test with one IM not ready?
Or keep driving it or should I reset monitors with a scan tool?
No CEL light after MAF replacement.
Thanks
