2005 GMC Envoy 6 cyl Two Wheel Drive Automatic 79900 miles
Auto zone connected their tool to it and it shows secondary injection malfunction
there are no changes in the way the vehicle drives or operates.
no weird sounds either
they turn the light off and it comes back on the next day with in 4-5 minutes of the same time it came on the day before
have the same problem?
