[QUOTE="91Eunos, post: 1880462, member: 29616"] Did the plugs, nothing out of the ordinary. Definitely worn, but not ridiculously so. Here’s the plug from the #1 cylinder (the one that threw the code), next to a new plug: [ATTACH type="full" alt="608E6851-4FE4-4B31-ADB6-F2BCFB2A3A9E.jpeg"]394632[/ATTACH] I took individual pics of all the others too, but all looked about the same to me. Here’s a group pic of all six; in order from top to bottom, 1-6 : [ATTACH type="full" alt="EF0BF52A-75F9-4356-8DA4-3E0E768842DA.jpeg"]394633[/ATTACH] Nothing unusual noted on the coils or boots, no cracks or indication of over heating, and the boots were still very supple. I also started and ran the truck for about a minute after each plug was changed, just in case I didn’t get something right. So far, so good…. No codes and it seems to be running very smoothly. Gonna take my wife out to dinner in a bit, and will get into the boost a bit during the drive as well. [B]edit:[/B] back from dinner, and did several moderately hard pulls in normal and sport mode…zero issues! [/QUOTE]
