Chevy Trailblazer 203 w wheel drive: my car runs good but when it runs for a while maybe 1/2 mile or so the engine shuts off while driving. This has happened several times now.
Check engine light stays on. Code showing is 134 what does this mean. Am older women and afraid to drive on the highway because of this.

P0134 is the O2 sensor circuit. Most mechanics can fix this and it won't effect your driving only your fuel mileage may suffer a little til it's fixed. Also have him check your fuel pressure.
