Bad to run with CEL on???
I just installed a Greddy turbo kit on my 97 Civic and didnt make a second hole for the second O2 sensor cause Im running a straight pipe with No Cat, so the CEL is always on. Would this affect performance and gas mileage?
Should I make a second hole for the o2 sensor and still use the straight pipe? Or should I install a Cat with the second o2 sensor? Or just leave it the way it is cause the CEL will not affect anything?
