i thought it was the 2v 5.4s that had spark plug issues, or do the nbs 3v 5.4s have em too?

 

Yeah, that new Silverado/Sierra is coming on strong...

It's like I see as many of them as I do the old bodystyle Silverado/Sierra- and they've only been on the roads a few months. No wonder, since combined they out sold the F-series by nearly 60,000 units.

Congrats to 'Yota as well. More than doubling their 2006 sales, Y/O/Y.
Props to Ford as well, still hanging on (Owner Loyalty) during the onslaught of the competition.

 

It's a different issue though, the '04+ models have a problem with the plugs seizing and then breaking in the head. The earlier models would blow the plugs out.
