Hi, i've got a bunch of CELs flashing at the moment,
don't have a helms for this model civic(only 92-95) so i duno what they mean.

couldn't find em via search either.

if someone could point me to a list of cel code descriptions, or even just let me know what these mean, that'd be great,
thanks.

codes: 65, 72, 74

65: Secondary oxygen sensor heater wire (black wires)

72: random misfire cylinder 2

74: random misfire cylinder 4


Sounds like you need to do a tune up, new plugs, new wires, and reset your ECU. You may also need a new secondary 02 sensor. Its throwing a code just for its heateing components, so it may be a frayed wire somewhere, so give that a check.

Hmm,
now that you mention that.
I thought that the obdII codes were different than obdI ??

I believe their both the same, just with OBD2, there are extra codes added in there, such as secondary 02, knocks, and EVAP valves
