Corolla BZ 20 valve idling at 1500rpm To high?

I'm sure it is supposed to be around 800 to 1000? Whats the fix? Also still getting a flat spot on acceleration sometimes. Put fuel cleaner and injector cleaner through but its only improved it a bit. Put.ting the Ac on brings the revs down

Is the thermostat working correctly? If not, it could be running on cold start idle speed.Change thermostat if necessary.

oxy sensor or idle control valve.

Air leak between the afm and throttle body, if it uses an afm.

i had similar on a 3sge celica.
tried a few things, everything made it abit better until it was smooth.
cleaned throttle body and idle control valve properly.
changed plugs.
replaced faulty thermostat.
adjusted timing.

then it idled but i still had a flat spot between 2 and 3.5k rpm
replaced leads, cap and rotor and its much better now.
