I have a 2007 chevy equinox with about 130,000 miles. We just took a long trip and service stabletrack and traction control is on dash. I have changed the EGR valve and battery unplugged for 10 minutes. Service lights are still on. Vehicle still drives with no issues. Same as before i changed EGR valve. Any suggestions??

 

I own a 201Chevrolet Traverse , my reduced engine power light was flashing and I could not reach speed greater than 40mph. It was placed on the computer, however the light had gone off by this time so the computer did not show a problem.
I begin to research the issue and found that it could be the battery or spark plugs causing this issue along with a host of other things. We replaced the spark plugs which was a chore in itself. Happy to report no trouble thus far. Thank God!
