Trailblazer EXT LS 4.2L

  • Automatic transmission
  • 105,000 miles

I purchased my 2004 Chevy Trailblazer used with 105K miles. When I purchased this vehicle used in 6/13 my code reader showed a bad oxygen sensor. I took my Trailblazer to a local shop to have the oxygen sensor replaced, which cost several hundred dollars.
