Healing

Sometimes when I go to start the 7, it sounds as if the engine keeps turning as if it were to start normally, but then dies before startup unless I give it some gas on the throttle. It's doesn't really seem like a problem, but more like an inconvenince...as if something might be going wrong? I've also noticed that my startup sequence hasn't really been activating. It used to rev right up to 3000 rpms right at startup, stay there for a few seconds, and then slowly bring itself down to ~1000 rpms. Now, it kind of half-heartedly brings itself up to maybe 2000 rpms or so, and kinda settles down around there. What could be going wrong? Thanks in advance.
