Default Throttle body relearn?

Anyone know of a throttle body relearn process for 1uzfe(95 LS)? Gonna clean my throttle body and I was wondering if there was a relearn process.

thanks

no fly-by-wire here, so there is nothing to relearn as it's controlled by a standard throttle cable.
there is a idle control valve that gets gunked up causing high or low idles. that one is ECU controlled which does learn to an extent.

Oh yeah...it is run by a throttle cable. Duh...on my end. Im sure only an electronic throttle body would need a relearn process. Ill clean up that IAC valve as well. Thanks timmy0tool
