Timing chain done...now a rough idle/low power issue! Help!

[csdcowboy]

Alright well I did the timing chain kit on my stock ka24e this last weekend (using http://www.240sx.org/links/installs/timing_chain/). Went fairly well, but took like 12 hours (that includes driving around getting things we forgot...doh!). She started right up and no rattle....oh so nice
Anyways, she's running rough at idle. Sounds kinda like a V8 or something, so I'm assuming it's missing. The reasons for this that I've come up with are:

1. I cracked the mount on the distributor when I was replacing it because I tried to mount the dist. with the spindle indside the front cover. It didn't crack all the way across, but it's pretty substantial. I'm thinking maybe that's throwing my timing off or making me miss or something.

2. I've done some researching (here, mostly) and now I'm wondering if maybe it's the MAFS?

Anyone have any other ideas, things I can check? I've got a new dist. coming in the mail, so that'll be fixed. Any knowledge is appreciated
