Good Spark, No Start

I have been surfing the forums and haven't quite found the answer I'm looking for. So I recently rebuilt my throttle body to fix high idling, I was able to crank it back up and run it. Then a day later, I cranked it up and let it idle for around 15 min, then I cut it off, at which point in dieseled pretty severely and now it won't start. I got spark and fuel going into the intake. Any ideas?

Update: So I disconnected the injector and it started right up, and would idle smoothly indefinitely. I then put the wire connector back on and restarted, very rough idle but works ok at open throttle. I looked in the throttle body with the injector connected, and it looks to be putting too much fuel in at idle. Is this a sign that my injector is bad/leaking? Or could it be the IAC? How can I check to isolate which one is causing the problem? I know the temperature sensor is working properly since I tested it with a mutlimeter and got good readings. Got to love the TBI
