Ignition problem, out of ideas.

Looks like my 2wk old Bosch platinum plugs were the problem. Read on here and corral that they seem to make the 5.0's run like crap. I replaced my old autolite 25's with the bosches just because it was time, now i've got new 25's back in.

I didnt see any cracks in them (bosches) when I took them out but one of the screw on tips seemed to be loose inside the porcelin.

Good call and that does happen to some folks with plats.

Good luck.

Welp the car re-broke during the night time. The next morning it ran like a 5 cylinder, tach went absolutley berserk.

I took the 1 year old plug wires off and every single one was dry cracked. Went and got some new ones.

FIXED, tach and all.

FYI, Autozone Duralast wires only last one year. I've replaced them with another free set of lifetime warranty duralasts until I get some real ones. Figured Id take the free ones for trouble shooting purposes.

And bad plug wires will make your stock tack crazy.

Thanks for all the help everyone. All is good in the world.
