1993 Accord-problem when first started in the AM

Car has 190,000 miles--runs fine when warm--however--when stone cold (in the
AM, been sitting all night-location Central Florida so it is not freezing
cold) and first started in the AM it makes a "wheezing" or "sighing" sound
and lacks power--these symptoms persist until it warms up and then it is
"good for the day"--a "mechanic" in a "shop" wants to replace the "throttle"
for $500 (this car is fuel injected BTW)--a friend suggested that it may be
the idle air control valve and maybe some cleaning of the air intake and
throttle blades would help--any ideas or similar experiences?

TIA,

Vacuum leak?

Could be that when the car warms up, thermal expansion closes up the
leak. Try opening the hood when the car is cold and have some else
start it. Then listen around for a hissing or sighing sound. Feel
around the ends of hoses. The air control thing (throttle) has about a
million hoses attached to it. Or, it just might be loose and leaking
around the base. Maybe a new gasket?

I bet it is something simple like that.
