I have a 94 F-350 powerstroke 5 speed that I just got. This morning I took out an aftermarket security key thing under the dash that was irritating me. It starts and runs fine. I didn't like it because it had 12 wires cut and spliced with crimp connectors to the security module and 4 wires were left hangine. Plus the clutch interlock didn't work.
Anyway, everything seems fine but I checked the KOEO codes just for the heck of it and got a pass on the first set then when it got to the memory codes I got a code 911. I checked it twice to be sure and I'm confused. My book doesn't list that code. Anyone got any idea what it is?

 

911 is a pass code for IDM and injector circuits...no fault detected

 

Great! Thanks a lot for the reply. That makes me feel a lot better. I need to get a new book for this one. I have all the factory manuals for 93 and 97 but not the 94 yet.

One other question,

I'm thinking the power is down a bit compared to my 97 and I wanted to do some more testing but this one has the old EEC 4 connector on it. Can I still do the power ballance and buzz test on it and if so does anyone know if it can be done without a fancy scanner? All I have for that connector is a cheap old code flasher.
