ok heres the deal...the light came on before i replaced all that stuff...my friend just used a portable computer from his work and hooked it up to the harness behind my ciggarette ashtray, and it said something like "ok to drive, computer just throwing codes" and "catalyst at low efficiency"...now is this somehow related to misifiring cylinders? when i used the paper clip trick, i read 7 long follwed immediately by 6 short, which is code 76, correct? i replaced my 02 sensor on the cat (i have a carsound cat) using a 00 civic sensor wired to my original harness(both have 4 wires) could this be the reason for this code? thanks again guys

edit: the mini comp asked "would u like to reset the code?" and we did...but then the code came on the next day
