Okay i think my civic is fixed. took it to a shop and they tested the o2 sensors. They figured out that the upstream o2 sensor was going bizzerko because the sensor itself was bad. The downstream o2 sensor could not keep up with the readings from the front o2. Which sent my catalyst sensor and my evap sensor out of whack as well. I had the o2 sensor replaced today and have driven the 2, 10 mile drive cycles with no cel, YET...!!! going back to take my emissions test again tomorrow, wish me luck and thanx for all the advice!

 

Did you get a CEl every once in a while and all you had to do was turn the car off and then turn it back on and the CEL goes away. My car does that.

 

Glad you figured it out.

 

nice! lets us know how it turns out.
