Scotty, I have a 2017 gmc 1500 Sierra 5.3 4x4 with 86,000 miles. The check engine light is on and it is throwing the O2 sensor code. Would you recommend I try the Lacquer thinner method on this engine? The only reason I ask is that in the comments on your video all I see are small displacement mostly foreign cars.
Thanks much! Dave
