how long did you run the car? if you ran her long into closed loop i'd be thinking along the lines of an o2 sensor, tps sensor, map sensor..or some other sensor. how long has the car been sitting?

if you ran her for a short period i'd be thinking the injectors. i'd swap in some from another honda and you'll quickly see if thats the problem. if the fuel pours out or trickles it will not spark and you'll get the fouling and flooding. check the spark, compression, leakdown, etc. a bent valve could create and nice stumbling idle too.

thermostat?...not really.
