could be coolant temp sensor - EEC uses this to adjust whether its in cold start-up mode or not

could be bad TPS

could be bad IAC.

my bet is on bad/worn IAC
try installing new IAC module, they're pretty cheap.

Is it just doing it for a second or two and than leveling off or is it staying like that?
