Altho I have had my '92 for over 2 years, I freely admit to not knowing everything. What, please explain, is a "deleted ninth injector"? 
First time I've heard that term.

Thank you! Always good to learn something new. I gather - from the OP's saying the 9th injector had been removed, as if it was a good thing - that they were prone to problems? How does something like that factor into what he is describing as his current problem?

Classic IAC problem.take it out and clean it and see what happens. Make sure you reset it when you reninstall it. There was someone a while back that had the same issue and I didn't think about then but I still wonder of he didn't reset the IAC when he put in a new one.
If you look around and do a search there's a ton of info on cleaning the IAC and resetting it.

IIRC, you start the car by giving it slight throttle, let it run for ten seconds and then just turn it off while holding the throttle in place.
Don't order the TPS until you clean the IAC to determine that's the cause.
Please, unless you just want to throw parts at it. I doubt the TPS is your problem. That's why the car will run with you giving it throttle. For lack of a better way of saying it, the TPS already knows where the throttle is and bypasses the IAC, as it's no longer needed.
You need the IAC for idle only. Hope this makes sense.
