how do i reset the computer in gs300
To reset the alarm on a 1995 Lexus GS 300, first, ensure the vehicle is unlocked using the key or remote. Then, insert the key into the ignition and turn it to the "On" position without starting the engine. Press the lock and unlock buttons on the remote to synchronize it with the vehicle, or you can disconnect the battery for a few minutes to reset the system. Reconnect the battery, and the alarm should be reset.
You can reset the computer on a 95 Ford Taurus by connecting an OBDII reader to the vehicle. It can then reset all codes within the computer.

Could be the auto idle control valve, try cleaning before replacing (about $300). Another simpler possibility is the fuel filter,replace this first,
