Okay, here's the deal. The O2 sensor in my Elantra went, so I got a big 'ol 'Check Engine Light' going. I have to do my Emissions soon, but I *think* the instructions say that NO dash warning lights can be on (like Oil, etc.) I'm pretty sure that light will be a deal-breaker. Is there anyway for me to pull a fuse for that type of light, or will everything go black and be evident?? Thanks.
