Default 92' Manual SC300 will not idle!

So only after a week of fixing my no start issue, now i have a new problem. I
I was leaving work to go get gas last night ( it was on E) and as i coasted to a stop sign i reved it up to maybe 4k or so real quick, just because, and as the rpms came back down they just dropped all the way and it died. I started it back up and drove off, then at the next light when i stopped in neutral it died again, and now it just will not idle unless i turn my ac on, which even then its way too low. Before all this it idled perfectly. Does any one know what this is?

I was thinking maybe i sucked up some bad gas from the bottom of the tank because of it being so low but it runs perfect other than the fact that it wont idle. Does it sound like a IACV?

IACV? TPS? MAF? Good luck.

Unlikely due to tank running low. Sounds like fuel pressure is fine.

You could possibly have a vacuum leak. MAF system are really sensitive to vacuum leaks. I would just take it to a mechanic and let them handle it. Unless you have a smoke machine. Check engine light on?

I work in a dealership shop, so i do all my own stuff. No vacuum leaks and no CEL. like i said it ran flawless before, the motor has never been messed with.
I have a spare IACV off my spare GE that ill try and throw on it today.
