Yeah, Yeah, another code question
Okay,, pulled codes (koeo) today and got one that im not sure where to begin. Got a code 12 and code 31. Know what the 31 is about - egr valve not closing. however, the other one -code 12- "system cannot raise engine speed above normal idle" What could be going on with that? With a bad egr be causing this type of problem, or am i looking for another problem somewhere else? One bit of info, that may or may not be related, the last week or so - service light comes on at about 1900 rpms/ 70-75 mph, and flashes pretty much through that range. However, if im city driving or even going 80-90 at wot, the sel does not flash. the two codes i have are the only ones that come up.
im also wondering if because of the code 12 - im not able to continue the KOER self test- as when i run it, i get no codes , not even the engine ID codes.
On a side note, notice references to a 1989 5.0 "SFI" engine. Are all 5.0 in 1989 SFI or where there several options?
Thanks
