P1121 code

[intheric]

Tinkering around under the hood today and noticed a small tear in the air filter. Gonna replace that but code that be the reason I’m getting a P1121 code?
Was going to replace the mass air flow sensor since replacing parts is what I’m doing.

thanks!!

I tried another app that works with my OBD scanner and got some more info from that one. Attached screen shots.

drove it around the neighborhood. Idled wonky then smoothed out when I started. I haven’t driven it in a months time as the battery was dead and waiting on the new alt. Ran fine. I drove it like I typically would. Lots of hills and accelerated fine. Came back to the house, let it sit in drive for a few, no drop in power or anything. Put it in park, idled wonky once, then evened out.


I feel like I’m actually learning stuff while still being totally clueless to what’s going on...
