Car had been running rich with rough idle after first startup and eventually bogging down and killing. Ran the ecu test and the cat converter was below efficiency threshold on bank 2 but the code went away the same day. Cleaned the MAF sensors and the filters and now it doesn't run as rough but the rpms fluctuate, still very rich and black exhaust and there is a p010 code for a airflow sensor. What steps should I take next?

 

Do you mean p0100? MAFs may be bad.

First startup...what work did you do to it?

 

Sorry was under the car when I posted it, wasn't very thorough on my post.

No mods or anything besides new air filters. It's an 07 with 90k miles. The codes were a p0102. But this morning the cel was off :/
Car is confusing me, think it's on strike or something
