In this episode of Ron Ananian, The Car Doctor, Ron discusses a variety of car repair issues, focusing on two main topics: diagnosing a misfire in a 2007 GMC Yukon and addressing oil consumption in a 2013 Buick Verano.


2007 GMC Yukon Misfire: A caller named John described a misfire problem in his vehicle, which was showing random misfires on cylinders 1, 5, and 8. Ron guides John to double-check the diagnostic scan, particularly using Mode 6 data to identify marginal misfires that haven’t yet triggered the check engine light. He advises using basic troubleshooting techniques like moving spark plugs, wires, and coils between cylinders to isolate the problem, while stressing the importance of ruling out faulty parts. Ron emphasizes that misfires typically stem from ignition, fuel, or mechanical issues but can also be caused by computer or sensor malfunctions. He suggests looking at the Mode 6 data to identify subtle misfires before they cause a check engine light.


2013 Buick Verano Oil Consumption Issue: The second part of the show focuses on a Buick Verano with oil consumption issues and other smaller problems. Ron explains that GM's 2.4L Ecotec engines are prone to sticking piston rings, causing oil consumption. Although the vehicle is out of warranty, Ron proposes using a product called Stiction Eliminator, which may help free up the rings and improve oil consumption. The vehicle also had issues with the right front lug nuts, some of which were damaged or missing, so Ron suggests replacing them to ensure safety.

Overall, Ron emphasizes the importance of small details in car repairs and offers practical advice for diagnosing and addressing common automotive issues.
