Checked your Spark Plugs lately?

Looks like #5 had a leaking vc grommet that has since been dried up with I'm assuming some Bar's stop-leak product

$34, NGK standards, some effing around to get at the plugs, and voila - new truck. I don't get how people can neglect such a special truck Luckily the 3.4 just smiles and says "is that the best you can do to me?" :boxer:

How many miles on those? Mine currently have 50,000 miles on them since last changed at the dealer. Going on a 3,000 mile road trip soon so might change the plugs soon.

No idea! Too many! I would never gauge a plug change on KM, the old eye ball test usually shall suffice

I just bought the truck. It was in need of basically a full tune up. Did a complete transmission service and plugs thus far...night and day!

Rig has 350,000+ KM's.
