Has anyone ran RUTHENIUM HX in a 2007 5.4?
I see some thread post of like 2017’s and newer, running NGK‘s. But I’m wondering if anyone has ran NGK’s on the 2007 expedition Eddie Bauer edition. I’d really like to try to max out performance and hopefully get a little bit better gas mileage with a better spark which I think the NGK’s would do.- wildcard007

Spark plug issue, how prolific?
Hi all, We are looking for a used Expedition around the 2002 to 2006 vintage and the zooming spark-plug issue keeps popping up. How bad was/is it? Is there a percentage of the vehicles produced for each problem year? I see repair-guys on YT stating "I have replaced lots/hundreds/thousands,"...- Cam Driven

Misfire on No.7
Im getting to the stages where I’m going to start pulling my hair out about this misfire. From the top. I had a lean code, lean on both banks. Found some hoses off to the pcv so reconnected, believe the fault was sorted. Next up I got a bad misfire on number 7, first off I swapped out no.7...- David Potter
