A '99 Olds Delta 88 doesn't use an orifice tube system for the air conditioning it uses a thermal expansion valve. The location is under the passenger side dash in the heater/evaporator box. Unfortunately, you have to remove the dash to replace it as well as discharge the a/c system.
The orifice tube on a 1998 Oldsmobile Delta 88 is located in the air conditioning system, specifically in the liquid line between the condenser and the evaporator. To access it, you'll typically find it near the firewall on the passenger side of the engine compartment. It is usually inserted into the line, making it somewhat hidden, so you may need to follow the refrigerant lines to locate it.
At the end of your air cleaner tube is a square box with 4 screws and a plug in. This is your mapp sensor
The orifice tube on a 1997 Oldsmobile 88 is typically located in the liquid line of the air conditioning system. To find it, trace the line from the condenser to the evaporator; the orifice tube is usually situated near the evaporator inlet. It may require some disassembly to access, as it is often housed within a fitting that connects the two lines. Always ensure the system is properly evacuated before attempting to replace the orifice tube.
