A vacuum leak, a misfire or damaged wiring can sit behind a check engine light, a rough idle or poor fuel economy just as a worn oxygen sensor can, so find the cause before you buy. This listing is one sensor; the number a car takes depends on its engine, with one at each sensor position in the exhaust.
