My 2004 trailblazer check gauges light is going off while I was driving. When I put it in park the idle is high

Question type: Maintenance & Repair

1 Answer

65

My 2003 Envoy had been idling rough for a long time. First I went and had a tune up with new spark plugs - a little better for awhile, then two months later, had the fuel injector service. Still idled rough after a short while. Now my service engine light came on. Took it in and diagnostics said bad thermostat. Had thermostat, engine flush, radiator flush done today. Seems to being running fine. I will post again to see if I have any more problems with rough idle
