1992 940 irregular idle and revs between 1500 to 2400 rpms s
new to forum: i have a 1992 940 non-turbo. it has idled rough at times but runs well with just a hint of a miss. now if you revv it up in park or neutral it stays around 1500 rpms and does'nt idle down and revs up to 2400 rpms then back to 1500 then up to 2400 etc. does anyone know what is happening...
