problem #1

Jul 302010

Trailblazer LS 4.2L 6 cyl

  • Automatic transmission
  • 142,000 miles

this problem also has the service engine soon light on, tune up has been done. has anyone else had this problem? also had transmission overhauled, replaced an overpriced electronic fan clutch, plus interior trim pieces falling off. I'm a big gm fan but wouldn't own another damn trailblazer as long as i live.
