engine trouble codes

I have a 95 F150 4x4. The engine check light came on I checked the codes and it sent me a 328 EGR closed valve voltage lower then expected, and 322 insufficient EGR flow detected. I also checked the IAC because the idle is funny and the voltage reading on it with the ignition on was 0.9 and the book says it should be 10 volts does the IAC need to be replaced or could it be wiring giving the low voltage

Did you make sure you were on a 50volt scale and not a 100volt scale? If the EGR is acting up, that will make your idle funny.
