I have a 98 civic lx and 5 months ago i had a full exhaust system put in. DC Sport headers, aftermarket cat, and Greddy exhaust. Because of the position of the o2 sensors and the cat it has tripped my check engine light on. I reset my computer before i went to take emissions test so my check engine light would not be on and the test was aborted twice they said my computer had not checked it self internally and that needed to be completed before the emissions can be completed. Their computer said OBD11 readiness codes, the codes that were not completed were as follows. (Evap sensor,Catalyst sensor, and o2 sensor) can anyone tell me what i can do? Can i do emissions with my check engine light on? My codes that come up for my check engine light are fuel too lean and both of my o2's, will i fail? any info would be great
