Cool Jr. Mechanic, thanks fore the info I have around 50K on my"Brandie" now, the wife is driving it while I'mover here in the catpan. I'll do the plugs when I get homeon leave. Nice to learn about the plug wires too. I'm way old school, I won't do anything that will mess up the truck while it's under warrenty, then again most of my "beaters" I could just about run cooking oil in them and re-file the plugs and they seemed to work.
