Engine Performance problem
2004 GMC Envoy 6 cyl Four Wheel Drive Automatic 92000 miles
my car has been acting up it stalls out when on the road stop and go. We had two techs put on computer and stated oxygen sensors were going we replaced both and added some fuel injection cleaner. It will not stay running now and it chugs and is sluggish. It runs very rough and the reduced engine power light is on and also service light on.
