Cylinder 1 misfire and slow o2 sensor
I have a "slow o2 sensor", according to o'reilly's, i can't remember if it was upstream or downstream though. Also about every 6 months or so I have to replace the spark plug for cylinder one due to a misfire. The arc thing or w/e in the plug is just completely gone and the spark plug smells of fuel and/or oil. The o2 sensor problem comes and goes, I usually leave it and the check engine light will go away after a while. Is their any correlation between the two? Is their anything else this might be? I need some help.
