check engine codes please???
 

hey, there is a 98 civic we are working on right now, we pulled the codes and they came up 66,72,73,and 74, can anyone tell me which these are? cause i cannot find them on c-speedracing.com anymore, thanks...

72,73 and 74 means cylinders 2,3,and 4 are misfiring.

ECU Codes

Sooo i was a little off.

actually it was a 67 not 66, but the carruns good, so what Im thinking is that in some point in time each of those cylinders must have had a mis-fire and they never cleared the codes, it cannot be mis-firing on all those cylinders cause it runs really good.
