hey guys, i put some aftermarket headers on my 94 civic today but couldnt get the o2 sensor off the stock headers.. so im running with no o2 sensor until moday (will buy one on monday). what will be the effects of running no o2 sensor? will it be okay to drive it around for a few days like that, coz i get a really bad burning smell.. nd how much will a new one be roughly?

also, i feel like ive lost alot of power.. is that because i dont have a sensor on at the moment?
