Bad idle and some cels

[diggler]

Ok, so here we go. I just bought this car about a month ago, and it was running fine then. Then i started to get a cel for catalyst effeciency below threshold, but the cat looks brand new, stickers and all, so i replaced the o2 in the cat. Now i have five cels 8 crank sensor is bad or not connected, 22 vtech malfunction, 45 too rich or too lean, 67 catalyst, and finally 72 #2 mis or random mis. This is all terrible for me, I'm not a bad mechanic but not at all familiar with honda and due to my newborn daughter i dont have a lot of time to devote to this at the moment. If anyone has any advice or a starting point for me i would be greatly appreciative, thanks in advance for any help

Digs

Oh, I should probably add that the car only runs rough while at idle. Any time I'm above 1k its smooth, no problems.
thanks again

check plugs

also, your numbers don't look right. Should be letter followed by four digits.

His numbers are fine, he's not using an odb scan tool, he's just jumping the connector which throws two digit codes
