Won't stay going unless over 2k rpms...

Here's my problem, unless I give it gas and hold it over 2k rpms, the car will die down and eventually stall. It will hold under 2k without dying but only if i'm like blipping the throttle to keep it alive. So basically its either rev and let it fall down close to stalling, then rev again and keep going if i want to keep it under 2k at a stop, or keep my revs up over 2k to keep it from stalling. Now there are a few things I think could be causing this. One would be a major vac leak, which I can't find, but still has potential because I haven't been able to look much since my car is in a parking lot away from my dorm and its been freezing. My second option would be my TPS ******* up, since I got a CEL once for the narrow range sensor, which eventually went off. I'm going to check the TPS tonight and try again to spot any vac leaks, but there is more. One of my 720cc secondaries is leaking, could that be causing idle problems? I read somewhere of similar stuff going on with a leaky injector that was causing flooding, but mine isn't flooding when I turn the car off, and I don't know if the secondaries have much to do with a sub 2000rpm problem. Lastly, I read someone who had a blown apex seal that could run the car but not keep it going unless it was above 2k. I'm PRAYING its not that one. Any other suggestions for stuff to help me out before I freeze my *** off and check out everything? A compression test is soon in my future, and i'll be checking for vac leaks and TPS resistance. Can't really work on the secondary leaking injector now since I don't have a replacement with me, but that will be fixed soon. Thanks.

Only thing is, it must be one gigantic vac leak if I can't even hold it under 2k. I had a vac leak before and I could hold it hardly above 1k and it would be fine and not dipping down.

If an apex seal was bad, it would be much narder to start and would run really rough.

To isolate the TPS, unplug it & see if that changes anything.

Dump a bottle of cheap injector cleaner in the gas. The alcohol in it will absorb any condensed water in the fuel system.

Well its not hard to start, but when I run, sometimes its rough, not really rough, but some hesitations. I can run the car with the TPS fully unplugged fine?

How is the injector leaking? You mean you are leaking fuel past an oring/grommet or is it stuck open? Either way could cause a bad/no idle.

I think it gets stuck. I'm going to check the other stuff out anyways since I got a CEL for the TPS, so i'll report back with those findings.
