2006 Equinox intermittent loss of power
The Equinox has 136,500 miles on it , daughter has owned it for 5 years and put about 40,000 miles on it. It is used as a winter car the last couple years , so it sits a lot during the nice weather. I know , I told her to drive it a least once week. So starting to run again for the winter and it has a intermittent loss of power , which can last a split second or for a few seconds. The yellow triangle / exclamation point comes on and goes out. I have hooked up the scanner several times and it does not have any codes. It runs great other wise (slight heater core leak/cup a week) We had some rust repair completed on the running boards (under the plastic cladding) , driver rear wheel bearing replaced ,two new winter tires and state inspection completed. She is driving my HHR until I resolve this issue. I have ran it about 200 miles so far this winter. I drove it 60 miles today with the TC turned off and no issues. Any ideas?
