Default AIR Delete, Running Rich?

Deleted the AIR system (left the actual pump on as dummy pulley) and hooked everything back up and started it up and it was running rich.

Well I assume it was since it never smoked before and there was faint black smoke coming out and it would bog down when I hit the gas. So I cut it off and cleaned up the shop, and went back to pull it in an figure it out later. I cranked it and it ran great, took it around the block and ran great.

Does the MAF have to reset itself to the AIR not being there? I guess if everything is running well no harm no foul. Just wanted to know to better my C4 knowledge

Theres a fuel adder when the AIR pump is commanded on but its very small and shouldn't cause any issue especially at wide open.

I assume the only way to end that command is reprog the ECM? It was strange that it was bogging down on the 1st restart and then I let it sit for 30min and restarted it and it ran fine, thx for the tip
