Yes but, it is called an orifice tube.
The ERG valve is located on the front of the engine on a 1998 Chevy Blazer V6 4.3L. It is near the top bolted to the intake manifold.
The expansion valve, on your 1998 Honda Accord, is located just before the thermostat housing. You can follow the water hose from the radiator to the expansion valve.

Remove the bottom hose from the evaporater at the firewall, pull out the expansion valve, i highly recommend flushing out the system to remove excess sludge. Replace the valve and the hose.
The ac system on a Ram doesn't use an expansion valve. It uses a fixed orifice system.
The 1998 Blazer could have several problems causing rough idle. Check the air filter, fuel pressure, and EGR valve for a clog to look for the problem.
There is no expansion valve. There is an orifice tue. It is located in the inlet tube of the evaporator core.
It is located inside the evaporator case.
Assuming you're referring to the AC system, there isn't one... as far as I know, all model years of the Blazer (K5, S10, and the midsize model replacing the S10 Blazer when the full sized Blazer became the Tahoe) used a fixed orifice tube.
To replace the expansion valve on a 1998 Subaru Outback, first, ensure the A/C system is fully discharged by a professional to avoid refrigerant exposure. Remove the dashboard or center console components as necessary to access the A/C evaporator. Disconnect the refrigerant lines from the expansion valve, unbolt the valve from its housing, and replace it with the new one. Finally, reassemble all components and recharge the A/C system.
