my 96 f350 with 351w is giving me idle problems.i pulled the koeo codes and got 32,73,and 27,since i knew 73 had to do with the tps i changed the tps and re pulled my codes and came up clear.i decided to run the koer codes and i came up with a bunch of codes.i am not sure what they mean.41,53,85,36and 63 will someone define them for me? i think the 41 is oxygen sensor

 

A 96 with 2 digit codes? That would be very interesting since a '96 would be OBD-II, and should have 3 digit codes.

 

its a 96 according to the vin. however i think its a late production 95

 

If U have a F350 or F250 w/ a 351W and automatic the trucks run the old style injection system and have OBD1 style computer system. I bet your truck does not have mass air like a 1996 f150. And the plug is out under the hood, not under the dash. Hope that helps and you should get two numbered codes.
