Code 327
I have searched the internet high and low and have found little that addresses this code. I have a 1996 F53 Motorhome with a 7.5L engine. It wasn't lighting up the CEL until it started running so badly that I replaced the fuel injectors. Once they were replaced, the coach ran great but smelled rich and started illuminating the CEL intermittently while in operation. I purchased a code reader for the OBDI system and identified a problem with the O2 sensor, I replaced that then got another code that led to the replacement of the IAC solenoid. It no longer smells like it is running rich but now I am receiving a code 327 during KOEO in Continous Memory. This is the only code I am getting when I run a scan.
I have replaced the EVP sensor and the EGR was replaced within the past 5 years. Not finding much to work with on the internet, I'm a tad lost as to how to troubleshoot this. I saw mention of testing voltage but have no idea how to do this. Any help would be greatly appreciated.
Also, does anyone know what the idle speed should be? Mine is idling at about 950 RPM, up from 500 RPM since the replacement of the IAC solenoid.

950RPM is high. Is it that high after it is completely warmed up?
