Sorry, forgot to mention the TBs are clean(First thing I did). Ill double check the MAFs but I did looked them over but didn't see anything but it wont hurt to clean them. In the event that cleaning doesn't work (probably not knowing my luck) anything else I should be on the lookout for? I've seen some instances of the ECM failing (same symptoms I have), how real of a possibility is that?

ECMs seem to be very reliable but it's a possibility. Could be a dirty/bad injector. As per jchammond, it could be fuel pressure.
