Pulled Codes.... Please Help

[BowTie Eater 5 Liter]

Cars running rough, doesnt feel like its got as much power. it also smells very rich, and when im slowing down, if i put in the clutch, sometimes the rpm's will drop to about 500 then back up to 1000 and then filnally smooth out at about 700ish.

the car is basically stock, 1.7 rockers, 70mm throttle body, exhaust gears and some other minor bolt ons.

the codes that came up were 67, 10, 29, 33 testing KOEO, and 94, 44, and 33 with KOER.

not sure if its affecting anything, but i wrecked a speedo gear a couple weeks ago, and pulled it out and havnt been able to get a replacement yet.

if anyone could help me out with my problems, please let me know.

thanks!
