every car with a standard oxygen sensor could benefit from a wide band sensor. if you have a 2 or 3 wire sensor for about 70bucks and a search DIY on how to convert to a 4 or 5 wire wide band oxygen sensor now referred to as sensor oxygen meter,the old sensor told the ecu too lean or too rich , or the bang bang effect. the newer meters are capable of (metering fuel ) well the ecu uses the info to meter fuel. should be worth about 3 to5 % so you can figure payback mileage. note an oxygen sensor fails to properly cycle at around 70,000 mi , so you might need a new one anyway. cheaper and less hassle ,only about 2 to 4 hrs max.
