Thanks for the replies. I will check these and reply back.

I recently purchased a 1998 holiday Rambler endeavor with the cummins 5.9 isb and 6 speed allison trans. The motorhome runs great but for one problem. I went to start it this morning and the check engine light came on. Following the instructions to extract codes it read as 0372. After a google search this is “idle select high/low”. Does anyone know what this means and how to remedy it?
