This is my problem. My CEL turns on intermittently. When the car is cold the CEL does not come on. When I drive about 35 miles or so it comes on. I don't notice any change in performance. I checked the code once I parked and it flashed once for about 2 seconds and then a long pause then flashed for 2 seconds again. I'm sure the code is repeating. I am confused though as to what code it is throwing. I read many posts about interpreting codes. I read that long flashes are first for a 2 digit code. But in my case there is only one long flash and nothing to follow. Does this mean it is throwing a code 10? Short flashes indicate 1 digit codes but no short flashes occur. I just switched out my O2 Sensor so it couldn't be a code 1. Please help me interpret this code. I'm hoping it is something simple.

 

its prolly o2...had the same problem with my crx after the lady i bought it from told me she had just replaced it, i replaced the o2 3 times and it still occured so i said fuckit, took the dash apart and pulled the cel bulb out of my dash. you can try pulling your computers main fuse, which is what my repair manual said to do, but it just kept coming back.
