Recently i've put about $5,000 into my bull in repairs. Rebuilt transmission, new EPA sensors, new coil springs that snapped, replaced rack and pinion, etc... and now my O2 sensor went out on me and i have absolutely no money to pay $70 for a new one. And with gas reaching $2 a gallon i can't afford for my MPG to decrease. Does anybody have a used O2 Sensor for a 99 vulcan that they would be willing to donate if so contact me, i gladly appreciate any help what so ever.
