What's wrong? Have to hold throttle wide open to start hot engine?

The sensor send to the ECU the info that the engine is cold when in fact it is hot. The ECU sends to much gas and floods the engine (too rich a mixture).
That's why you can start with the pedal to the floor : you give the engine more air and that leans the mixture.
A possibility to investigate.
The fact that there's no CEL is strange though. When that happened to me (same symptoms) the CEL had been on for quite a while.

You can get one for 20 bucks at libertysubaru www.newsubaru.com
you can pull the codes & do an active diag mode. Instructions on my site.
For the money, I'd probably just replace the temp sensor.
