Well tried the autolite plugs (3923) for my 7mgte. Sure enough, the damn thing misfired. I thought maybe i gapped them wrong, but my neighbor a mechanic checked them out 2 were slightly off so we got them all to .031. Still misfired. So, these damn plugs didn't work and i wasted an ass load of time, god im pissed lol. What is the plug the book recommends? Anybody know offhand. Thanks.
