yeah im pretty sure i did that but i want to try it again, but now when i go into recovery mode, CWM doesnt come up. I only see the android robot opened up with a exclamation mark on him. any idea what that is
That is stock recovery. You didn't actually flash CWM recovery. You must have booted into it (I prefer TWRP).
I would advise you to use the Nexus 4 toolkit from XDA and flash TWRP/CWM. Then you can install ROMs right on the device without needing to boot into a custom recovery with a PC or mac.

Actually, isn't that fastboot mode? If so, you should be able to use the volume buttons to scroll down to recovery and select with the power button. If CWM recovery doesn't open then Michael is correct in that you didn't actually replace stock recovery with CWM. I've used both CWM and TWRP and both seem to work fine, though I think some developers prefer one over the other for their ROM. The latest ROMs I've been using suggest TWRP so I've been using that.
If you are in fact already rooted, you can even install GooManager from the Play store and install TWRP right from the app.
