Hi,
my friend has a 99 dx,
all stock.

car seems to drive fine but his CEL popped up,
I jumped the service check connector and it showed code 67.

I have a service manual but it's for 92-95 civics, and I couldnt find code 67 in it(well it might be in there if I really hunted it down harder).

Do you guys know what this code means?
I reset his ECU and the code went away(although not immediately).

But now he's mentioned that his idle seems low(even though he has no tach).

Thanks in advance.

hmm, according to that cspeed list(thanks for the link btw thats handy)
the code 67 is only for 96-98 civics?

All Honda Codes are pretty much the same...it says on cspeed only for 94+ Integras, but all b series motors throw the same codes and I would assume that the d series motors would do the same.

ok,
also could it be that he hasn't changed his oil in like 10k miles?
