Having problems with your 2002 Pontiac Grand Prix ?
Have to replace O2 sensor ( 2003 Rendezvous ) will I get better mileage afterwards ? An any idea how much it can cost for the part and to replace it by a mechanic ? Thanks for all your input ...
$70 down stream and $5O Upstream are average prices. about 1,25 hours of labor. Good mechanics can test these for malfunction.
