Hi Toyota283

Clean out the carbon deposits in the idle port using decarbonizer spray also the throttle plate. Use a DVOM and get voltage readings from the IAC plug, remove any engine codes and please post them. Remove the IAC and connect the plug to it, by turning the ignition with KOEO several times check the IAC if the plunger moves in and out.

post back your findings.

Good chance you'll have to have the computer R & R'ed at your local parts store.
